[Entrance]
00:26:495 (2,3,4) - Hard to read for Easy.
00:28:384 (5) - Remove slider whistle noise.
00:30:271 (1,2,3) - Hard to read as well.
00:46:834 (3) - Remove slider whistle noise.
01:47:009 (2,3,4) - Not vocally snapped on (2) and hard to read.
01:50:785 (1,2,3) - ^
01:54:770 (5) - Move forward to white tick?
02:50:123 (2) - Too far of a jump.
[Standard]
00:23:142 (4) - Replace with whistle.
00:30:271 (1,2,3) - (2,3) are not vocally snapped. Sounds bad too.
00:31:738 (4) - Remove slider whistle noise.
00:46:835 (1) - ^
01:14:304 (2) - Align directly above (1).
01:15:141 (3) - Align directly under (2).
01:50:787 (1,2,3) - Does not sound good using red ticks.
01:55:188 (3) - Remove slider whistle noise.
01:58:123 (4) - ^
02:01:898 (3) - ^
02:21:607 (1,2,3...) - No copy pasting... it gets boring.
02:50:123 (2) - Remove clap on return.
02:54:316 (4) - Remove clap.
02:56:832 (1) - Remove slider whistle noise.
03:02:075 (1) - Move back to white tick and extend to red tick.
[Hardcore]
00:31:738 (5) - New combo.
00:46:835 (2) - Remove slider whistle noise.
00:56:060 (3) - Remove clap on end.
01:00:044 (7) - Finish.
02:50:124 (2) - Remove clap on return.
03:01:865 (1) - Move back to white tick and extend to red tick.
Like I said, copy pasting is booring.
[Extreme]
00:31:738 (5) - New combo
00:46:835 (2) - Remove slider whistle noise.
01:20:382 (1) - Remove clap.
03:02:075 (1) - Move back to white tick and extend to red tick.
A few of the things here are the same as [Hardcore], which is really boring. Have variety in between your difficulties.
Also, maybe speed up the slider velocity?
