[General]
Needs an approach circle to complete the set.
Countdown doesn't fit that well, since it's pretty loud, and the start of your map's pretty soft.
[Easy]
00:53:424 (3) - Doesn't look too good. When you use a red point on a slider, the two points on both sides of it needs to form a straight line, or it doesn't look smooth. Dunno if I'm saying something you already know.
03:52:818 (1,2) - These two sliders could be made to look neater.
04:21:909 (1) - Repeat's placed in a kinda-weird spot.
[Normal]
00:29:788 (2) - The claps here are quite jarring; they're a lot louder than the normal hitsounds.
00:41:909 (2) - A grid right to lineup with the end of 1?
00:43:727 (1,2) - Your spacing in this diff changes a lot. From 00:41:303 (1,2), which is 0.6x, to 00:36:455 (1,2), which is 0.75-0.8x, and this, which is 1.0x. I think it would be best to go through the diff and make these more consistent, since now some touch, some don't, and that's confusing for Normal. Your lowest is nearly half your highest, and it's the same musical section.
00:48:576 (1) - Change this to not be linear and instead to blanket the 6?
http://puu.sh/4An6 (except yours should look nicer than mine, since I took like, 5 seconds for that)
01:16:455 (1,2,3) - A reminder for consistent spacing.
02:11:606 (3,5) - Maybe switch these notes, so that the 3 doesn't end up under the slider?
02:21:909 (2) - Moving the last point a few grids right can line this up with the 3,4.
02:30:697 (2,3) - Hard to read the spacing for, since it's more intuitive to read the head2-3 spacing than the tail2-3 spacing.
02:52:212 (5,6,7) - Line all 3 up, not just the 6,7.
02:57:061 (5) - Curve this a bit more so that 4,5 line up.
02:59:485 (1,2) - 5-point sliders can help you make a better circle here.
03:29:182 (5,6) - More spacing inconsistency.
03:42:212 (1) - Hard pattern to read for Normal.
03:56:758 (6) - Still haven't decided whether 1/2 should touch or not.
[Hard]
00:43:727 (2,1,2) - On all your maps, there's a lot of places where you seem to want to line something up, and then miss by a grid or two. I think you should look over them all and tighten them up; my Normal mod looked a lot longer than it should be because of that (and because of inconsistent spacing), so I'll stop mentioning them everywhere now.
00:58:879 (1,2,3) - This map kinda also suffers from the same inconsistent spacing (anywhere from 0.6 to 1.0) issue, but as a Hard, it's not as noticeable. Should still look over that though, won't keep mentioning it either. Oh, but this 3-4 jump should be marked with a new combo.
01:17:061 (5) - Ignore what I said before, this is really noticeable, and I don't know why spacing suddenly shrinks here.
02:42:818 (8,1) - This blanket could be tightened up too.
03:50:091 (4,5) - I'd recommend not stacking these two notes; stacking breaks your symmetry.
04:24:940 (7) - Stack these two ticks here.
CDFA's sliders were really good, you should ask him to show you how to make awesome sliders; some of these sliders are a bit off from symmetrical, or a bit off from looking "right".
[Taiko]
Needs a resnap.
[Collab]
Drain is too high, you don't have the notes at the beginning to sustain 7 drain. (I was dropping down to 60-80% bar at times when I was SSing, so those 100s will hurt.)
Some parts look/sound better with 4 tick rate, some don't.
HellDawn:
00:43:424 (3) - Concealed slider repeat.
00:50:697 (2) - ^
Pereira006:
01:33:424 (1) - Shorten by 1/4, like the previous one, and add a note?
HellDawn #2:
Hitsounds seem really sparse.
Debbiee:
02:32:818 (1) - Really dangerous with no warning, since the other mappers didn't do this. If you don't, you might as well delete the two timing sections after the first fast slider and before the second one, since it's not like you have any 1.0x sliders in between anyways.
Nivalis:
This one section is significantly harder than everything else. Dunno if this was intentional, but this doesn't usually happen in a collab.
02:49:030 (1) - Caught me offguard; didn't expect this to continue at 1.5x.
03:41:909 (1,2,3,4) - And this jump is brutal. Liveable though.
03:52:667 (1,2,3) - These jumps don't fit the music; they land on points that don't really make sense to have a jump on; in fact they all land on blue ticks. I can clear it on my second try, but it was really surprising on my first.
Poor CDFA, left out of the collab. T_T
Overall, this set needs more modding, imo.
