[General]
Consider changing the background colour to black.
You might want an Easy.
[Normal]
00:44:026 (2) - Adjust this a bit to line up properly with 3, 4, 5.
00:46:027 (2) - ^
00:48:080 (2) - Turn off grid snap to nicely line this up with 1.
01:43:027 (1) - Replace this with a reversed copy of 2.
01:58:091 (2,3,4,1) - Looks weird, slightly off being a straight line.
[Hard]
00:37:045 (4,5,6,7) - Didn't think these sounded/played very well.
00:42:099 (5,6) - Quite surprising, lol. (also for these you could turn off grid snap and align them better)
00:54:060 (5,6,7,8) - Not the greatest part. Also, slant them a bit more so that 1-2-5 and 5-7-9 become nicer triangles?
02:14:004 (3) - Move this around a bit so that the endpoint lines up better with the stack.
02:18:033 (1,2,3) - Looks a bit weird; either adjust them so that 1 can fall on the endpoint of 3, or just don't put it horizontal like that.
02:37:075 (4,5,6,7) - Still don't really like this pattern.
02:40:027 (1) - Maybe replace this slider and the area around it with a few notes; it's slightly hard to predict when it'll fall.
[ignore's Insane]
01:37:098 (11) - Note sounds a bit weird by itself, maybe add 1 or 2 notes after it. (on the 1/4s)
02:06:098 (4,6) - A bit misaligned, intentional?
02:16:069 (9,10,11,12) - Curve this a bit smoother?
02:28:067 (1,2,3) - Spacing's off by a bit, turn off grid snap and respace the 2.
02:29:043 (5,6,7) - ^
02:30:018 (9,1,2,3) - ^
02:31:044 (5,6,7) - ^
Nice overall, star~
