HP Drain -1 maybe?
AR -1 or -2.
OD -1.

00:00:340 (1,2,3,4) - Map this in a diamond! http://puu.sh/54rS
00:01:610 (5,6) - Try making these sliders more round and clean. Use more points; ctrl + left click. Consider moving (5) left a bit as well; over (4). Example: http://puu.sh/54st
00:04:785 (6,7,8) - Are these slightly diagonal on purpose? If not, make this linear along the horizontal.
00:06:055 (2) - Rotate this nicely above and along (1) and (3) of the same combo. http://puu.sh/54sY
00:07:642 (1) - Consider dropping a note here which will make it (4) of the previous combo.
00:07:642 (1,2,3,4,5,6,7,8) - Consider moving this whole section (highlight and drag) over a whole count of 4. Looks like this: http://puu.sh/54tB ; make sure to fix your green timing points for the repeat sliders here, and watch the spacing between (8) and the beginning of the next combo.
00:11:134 (2) - Round the slider properly.
00:11:769 (3,4,5,6) - Make into a triangle so it looks cleaner~ http://puu.sh/54ug
00:15:261 (8,9,10) - Sounds a little too cluttered or extra, try adding hitsounds to it or remove (9), it sounds much better.
00:15:420 (10) - You could always stack this on (1) of the next combo. (following the previous step) http://puu.sh/54v2
00:16:848 (3) - Move this slider up a little and over left; http://puu.sh/54vd
00:17:325 ( ) - Useless green timing point.
00:17:483 (4) - Make this slider similar to (3) of the same combo; you could copy/paste it so it's A LOT easier.
00:18:118 (5,6,7) - New combo?
00:20:182 ( ) - Useless green timing point. Consider its removal.
00:21:293 (1,2,3) - Space these properly. Rotate (3) so it is symmetrical to (1). Copy/paste alone won't make it symmetrical so you'll need to clean them. Some more random green points along this. An image to help you out: http://puu.sh/54wS note that those sliders are not symmetrical, you can tell by the cutoff of the picture at the bottom.
00:25:102 (1,2) - Remove new combo on (1) and make (2) the new combo.
00:27:959 (1,2) - ^
00:28:912 (2,3,4,5) - More useless green timing points, and clean these sliders up so they are even along each other and not randomly placed.
00:32:086 (3,4,5) - Place (3) square in the middle of the grid, and move (4) and (5) symmetrically across (1) and (2) of the same combo.
00:33:039 (6) - Place above (3) on the vertical.
00:33:357 (7,8) - Place (7) somewhere between (6) and (8) of the same combo. You could make a trapezoid pattern with (5,6,7,8), like this: http://puu.sh/54zB
00:35:896 (7) - Snuggle this between (1) and (2) of the next combo~ http://puu.sh/54zV
00:36:848 (2) - Make this slider similar to (1) of the same combo? Also, move it down so that (3) can slide underneath it properly.
00:37:483 (3) - Place it like this: http://puu.sh/54Aw and don't forget to fix the slider!
00:38:118 (4,5,6,7,8,9) - http://puu.sh/54AG ^o^
00:41:293 (3,4,5) - Get rid of the whistles on (3) and (5). Consider removing (4).
00:41:610 (6,7,1,2,3) - New combo on (6), remove new combo on (1).
00:43:198 (4,5) - Fix these sliders, please >< also, new combo on (4).
00:44:469 (1,2,3) - Remove new combo on (1), align these properly in a linear pattern.
00:45:737 (7,8,9,10,11,12) - Fix this pattern. Consider the removal of (8). Add some hitsounds and new combo on (7) if you keep the pattern like this: http://puu.sh/54CR If you like the feel of (7,8,9), add a note between (11,12): http://puu.sh/54Dy ; http://puu.sh/54DJ
00:46:531 (1,2,3,4,5) - Fix (1) and (2) so they are symmetrical to each other along the vertical. Move (5) 1 grid space over to the right using grid level 4 because it is not properly aligned. Somewhat like this: http://puu.sh/54E5 Add some hitsounds >< it's hard to tell the pattern without it :< as well as more random green timing points?
00:48:912 (1,2,3,4,5,6,7,8) - Consider the removal of (1). You can easily symmetrically place the notes here. Extend sliders by one tick on both; don't move slider 8 timing wise. Add a note at the end of (8) on the white tick if you follow this. http://puu.sh/54EV A pattern for you: http://puu.sh/54FH
00:51:134 (1,2,3,4,5,6,7,8,9) - http://puu.sh/54Gv ; http://puu.sh/54Gj also, (9) needs a new combo. :3
00:53:991 (2,3,4,5,6) - Like this: http://puu.sh/54H8, and (4,5,6) here: http://puu.sh/54Hs
00:56:848 (4,5,6,) - Stack beginning of (4) on top of previous (5) and consider adding a note like this: http://puu.sh/54HW ; http://puu.sh/54Ia
00:58:753 (1,2,3,4,5,6,7) - move (5) and adjust (6) and (7) like this: http://puu.sh/54IC , and new combo on (6).
01:02:880 (5) - Move inbetween these sliders: http://puu.sh/54IL
01:05:420 (5) - Stack properly in the center of the grid.
01:06:372 (1,2) - Stack the ends properly and move the beginning of (2) to the centre: http://puu.sh/54Jh
01:07:959 (4,5,6,7) - Remove notes (5) and (6) so it follows the combo. Also remember that this diff is a hard. The slider also runs in with the next combo: http://puu.sh/54Qi and it's slightly ugly, so move the slider over to the right more. You could fix it like this: http://puu.sh/54Qq
01:09:547 (4,5,6,7) - Move these out move, and line up (4) directly across from (3). align (7) with (5) since (6) is a little lower than it. http://puu.sh/54Rf
01:10:499 (8) - Rotate this and stack it on (6) like so: http://puu.sh/54Rv (6 is underneath the ball~)
01:12:404 (1) - Remove new combo and put it under the stack of (1,2,3) from the previous combo.
01:13:991 (8) - New combo; I love that slider, Sekai! *-*
01:14:944 (1) - Remove new combo.
01:14:944 (1,2,3) - Move (3) properly under (2) and align it with (5) of the same combo to form a triangle between (1,2,3); adjust the placement of (1) to make a proper triangle at this point, and make sure it is in line with the end of the cool slider http://puu.sh/54S6 ; http://puu.sh/54S9
01:16:531 (1,2) - Stack underneath (3) of the previous combo, and adjust the placement of (2). Idea: http://puu.sh/54Si
01:17:801 (3,4,5) - Some really random green timing points around here. Also, fix the symmetry of these notes, specifically, move (5) over more or even redo the sliders.
01:19:388 (1,2,3,4,5) - Fix the placement of these notes, they are messy. (5 mostly is the issue~) Consider lessening the amount of notes here, it seems generally random in a hard diff.
01:21:610 (1,2,3,4) - Fix the placement of (1,2,3), and that repeat slider seriously needs to get fixed because the timing is wrong. Redo it or use green timing points (correctly this time Sekai, lol~) to change the slider velocity. Also, add hitsounds.
01:22:563 (1,2,3,4,5,6,7,8,9) - Stack these properly in a square, like this: http://puu.sh/55VP , stack (7) properly on top of (1) of the same combo and make a triangle with (8) and (9). http://puu.sh/55W0 Another solution would be to new combo (4,5,6,7,8,9) and place it like this: http://puu.sh/562J (You'll need to space out the last notes a little more to fit the pattern~)
01:24:785 (1) - Stack this on (2) of the previous combo, and see if you can stack the end on (3) of the previous combo as well: http://puu.sh/55WB (see how two and three are on both ends of the slider?) fix the slider here as well.
01:25:420 (2,3) - Stack the repeat slider properly on (4,5,6) of the previous combo, and place (3) underneath the repeat end properly. http://puu.sh/55WM ; http://puu.sh/55WN
01:26:690 (4,5,6,7) - New combo because of the difference in spacing.
01:29:864 (1,2,3,4,5,6,7,8) - Space this pattern properly, and (6) sounds really weird here, and the hitsound issue doesn't help. I would suggest shortening the slider, and adding a note at the end of it between the timing of (6) and (7). That new note will become the new combo. Space the new combo properly as well. Move (3) from the white tick to the previous blue tick for proper timing. Some images to help with the understanding: http://puu.sh/55XL ; http://puu.sh/55XU ; http://puu.sh/55Y5. Get rid of the random green timing point, please~
01:32:086 (1,2,3) - Stack these nicely under the previous (3) along the horizontal if you will. http://puu.sh/55Yo
01:33:039 (4,5,6) - Fix these sliders. Maybe take out the repeat in (5) and add another slider. Spacing like this maybe?: http://puu.sh/55YR
01:35:261 (7,8) - Place these properly along the vertical, and you can copy/paste either note to achieve proper symmetry.
01:35:896 (9) - Consider changing this slider, or doing something different at this timing to keep with the pattern of notes on the white ticks. Get rid of this timing point: http://puu.sh/55ZC This could work: http://puu.sh/55ZM ; http://puu.sh/55ZT
01:37:166 (1,2,3) - Copy/paste either (1) or (3) and mirror it on the vertical properly. Place (2) properly along the vertical as well.
01:39:071 (4,5,6,7,8,9) - Place (5) symmetrically to (4), and put both along the horizontal properly. Stack (6), (7), (8) and (9) on (4) as well, and see if you can connect the end of the slider to (5) of the same combo. http://puu.sh/5618
01:42:245 (1,2,3) - Place these around the previous slider neatly, like this maybe: http://puu.sh/561u You'll definitely need to move (1) down because of spacing issues.
01:43:198 (4,5) - Fix (4) to match the spacing between (1,2,3) of the same combo, and adjust the spacing of (5). This works: http://puu.sh/5636
01:47:325 (1,2,3,4,5) - Consider fixing the spacing between these sliders and making them a little more symmetrical or cleaner. Here are some ideas: http://puu.sh/563x ; http://puu.sh/563C (stacking four on the end of two looks lovely imo) ; http://puu.sh/563R (Stack the beginning of five on the beginning of two of the same combo, it keeps the flow)
01:50:499 (6,7,8,9,10) - Create a triangle out of this; keep (6) parallel to the beginning of the (5) slider and stack (8), (9) and (10) on it as well. http://puu.sh/564m ; http://puu.sh/564p (fix up the repeat slider here, in the picture I fixed it slightly but it could look better.)
02:03:515 (1,2,3,4,5,6) - Get rid of some of those green timing points again. Add some hitsounds here, and fix the symmetry between (4) and (6). http://puu.sh/566Z
02:06:055 (1,2,3,4,5) - New combo~ more green timing points that need removal = =. (6) needs a new combo. Consider fixing these sliders.
02:08:594 (1,2,3,4,5) - Remove new combo? (1) and (2) should be fixed, try making them rounder and copy/paste one slider to make them similar. Even make these sliders a replica of the previous slider if you'd like. Place the beginning of (1) parallel to the previous combo. http://puu.sh/568b (it's hard to tell the symmetry here, but it's there =w=) ; http://puu.sh/568s
02:11:134 (1,2,3,4) - You should move these closer to (6,7,8) of the previous combo, the jump is quite large. Make sure these make a lovely diamond pattern~ add a note to fill in the gap of timing here are some images: http://puu.sh/56aJ ; http://puu.sh/56aK
02:12:404 (5,6,7) - Straighten (5) and move it closer to (4). Copy/paste (7) and mirror it. Place the beginning of (6) on the (2) of the same combo, and stack (7) on the (4) of the same combo as well. http://puu.sh/56a1 ; http://puu.sh/56a4
02:14:309 (1) - If you make the previous sliders symmetrical and more clean, you could do this since it follows the flow of the beat: http://puu.sh/56ao
02:14:944 (2,3) - Fix these sliders and move them closer together. Here's an example: http://puu.sh/56aS
02:16:904 (1,2,3) - Fix the angle of these sliders, and try to make them the same (use copy/paste). Even something like this is acceptable: http://puu.sh/56bz
02:18:753 (1,2,3) - Whatever you do to fix the above, ^ fix the placement of these as a whole.
02:19:388 (1,2,3) - Make (1) and (3) parallel to each other. If you have troubles, align their beginnings along the vertical.
02:21:293 (1,2,3) - Get rid of the random green timing points here, unless you use them for some other purpose such as adjusting the volume of the hitsounds. Stack these on the beginning of slider (2) of the previous combo.
02:23:832 (1,2,3) - Are these purposely on a slight diagonal? If not, fix this.
02:24:467 (1,2,3) - Make similar sliders. Space them evenly, too.similarsliderssimilarsliderssimilarsliderspleasepleaseplease~
02:26:690 (1,2,3) - Move these over to the right more so they don't interfere with the next combo. Align (1) with (2) and (3) as well. Make sure (2) is even along the vertical, and they are in line with the end of the next sliders (see next picture for reference.)
02:27:325 (1,2,3) - Space these equally to keep the flow, and align (3) with (1) properly. Align (2) along the vertical. http://puu.sh/56cY
02:29:229 (1,2,3) - Fix these notes so they look clean, fix the spacing from this combo to the previous, and remove that green timing point. An option here would be to stack (1) on the beginning of (2) of the previous combo. http://puu.sh/56dg See how (2) shows up as (2)? It's because it's stacked. Spacing idea: http://puu.sh/56dn
02:29:864 (1,2) - Fix sliders, you could stack the end of (1) on (3) of the previous combo, and the beginning of (2) on (1) of the previous~ http://puu.sh/56eL
02:31:134 ( ) - Add a note?
02:31:452 (1,2,3) - Align (1) and (3) properly and (2) along the vertical correctly.
02:33:039 (4,5,6,7,8,9) - I'd suggest a different pattern here. Also, add a note on the next white tick after (9) (should be a blue tick inbetween). Remove that green timing point (if it's there to remove kiai, keep it) and move the spinner to the next white tick. New combo on (5) as well please. Images: http://puu.sh/56gN ; http://puu.sh/56gR ; http://puu.sh/56gT ; http://puu.sh/56gV green timing point gahhh >< Play around with the ending of the spinner since it's hard to find a good point to land it on =w=
