00:01:489 (3,4,5) - Would look better as a triangle pattern (120° between the sliders)
00:05:239 (3,4,5) - ^
00:08:338 (5,1) - This jump was weird to play and the slider overlapping 00:08:186 (4) doesn't look good as well. Place the slider somewhere else or give it a curving that is nearly blanketing 00:08:186 (4).
00:09:252 (4,5) - This obtuse angle does neither fit the music nor the object placement before. I would suggest making the slider end above the starting point of the slider
00:14:125 (4) - This slider wasn't good to read because it gets overlapped by 00:13:364 (1)
00:15:800 (1) - Sliders like these don't really look good and it seems like the really old mapping style. Just use normal curved sliders instead.
00:16:562 (4,5,6,7) - Same thing with those obtuse angles, mentioned above. Make the angles sharper
00:23:871 (4,5) - ^
00:27:526 (11,12,13) - This jump doesn't play well because of the sudden change of angles (sharp - obtuse - sharp, doesn't play well). You can basically fix this by putting 00:27:678 (12) nearer to the bottom.
00:29:201 (3) - Same thing mentioned above with the "old style sliders". I guess you know which sliders look like that so I won't point that out again.
00:36:054 (2) - Not a good use of flow. Doing something like this:

00:36:663 (3) - Basically, more slider point emphasize the slider but this is an overuse of them. A normal wobbly slider like this:
http://puu.sh/kpPNN/50adb76db4.jpg would have the same effect (but you might want to slow the slider velocity down for this)
00:38:947 (5) - Doing something like this would create a nice oval flow.
00:39:404 (6,7) - Obtuse angle again. Make it sharper.
00:43:211 (2,3,4) - This pattern doesn't look well.
00:44:277 (6,7,8,9,1) - Same with those obtuse angles. I won't point that out again, you should know what's the issue with them now.
00:46:638 (2,3,4,5,6,7,8,9,10,11,12,1) - This spacing is probably too much for this difficulty but a normal accelerating stream that gets the same spacing at the end would fit
00:51:130 (5) - Not good to read because of the overlap.
00:53:567 (5) - ^
01:01:638 (1) - Yeah, mentioned above, just change it to a normal wobbly slider.
01:04:379 (12,1) - This jump doesn't play good because of the angles, make the angle sharper.
01:11:003 (2,3,4,5,6,7,8,9) - Too much spacing but a normal accelerating stream that gets the same spacing at the end would fit
01:16:257 (1,2,3,4,5,6,7,8,1) - ^
01:16:866 (1,2,3,4,5,6,1,2,3,4,5) - Make it so the sliders don't overlap that much, it was very confusing to read.
01:24:404 (2,3,1,2,3,1,2,3,1,2,3,1,2,3,1,2,3) - Those sharp angles + this high spacing make the jumps between the streams difficult, choose either sharp angles or high spacing.
01:26:155 (4,5,6) - Harder jumps would be more appropriate for this ending
