Hello~
[Insane]
00:26:348 (1) - clap
00:41:465 (1) - ^
01:07:598 (1) - finish on start
01:10:644 (1,2,3) - I think finish hitsound like this are kinda unnecessary. I don't hear any resemblance in the actual music really. Well, it's just my opinion though
02:31:738 (3) - I'd prefer this being a hitcircle instead
[Hard]
00:30:098 (1) - finish
01:07:598 (1) - finish on start
01:40:176 (6,1) - I actually don't like this anti-jump even if it's a quite obvious pattern
02:07:598 (1) - finish on start
02:13:457 (4,1) - same with this spacing
02:22:598 (2,1) - I'd use 0,6x spacing instead here
[Revy]
00:26:348 (1) - finish
00:39:473 (3,1) - this looks quite awkward imo
00:44:160 (4,2) - avoid overlapping?
00:57:285 (1) - finish
01:46:504 (3,4,5) - why this spacing? it's really weird
02:10:410 (5,1) - bid space change, but readable imo and doesn't look too bad either
02:22:129 (6,1,2) - I actually don't like that you mix different spacings so often
[Pie]
00:30:098 (1) - the first thing you do is stacking? place in in the center please
00:41:816 (1,3) - can you make them look prettier?
That's all~
Good luck
