Ugh such a long map... Imma only mod 2 diffs.
Insane01:04:940 (4) - add finish to end
01:08:408 (4,5,6,7,8) - whistle spam is never good. remove them.
01:14:131 (2,3,4) - arrange like this
http://puu.sh/vCWc and add a finish on 4
02:12:397 (2,3,4,5,6) - move further to the right due to stacking
02:23:148 - I'd add a note here because... kinda confusing without because the downbeat wants to be clicked.
02:39:622 (6,7) - move a bit to the left to make it look better.
03:43:610 (1,2,3,4,5,6,1,2,3,4) - can't you do something more innovative?
HardAR is kinda high, but your mapping makes it hard to play WITHOUT AR8. At least lower OD by 1.
Please add more claps. They are an important tool to keep a rythm, and will greatly improve your map.
00:47:079 (5) - add new combo
00:48:119 (1) - remove new combo
01:41:183 (6,1,2,3) - this doesn't look good and it plays bad.
02:00:605 (1,2,3,4) - weird to have 4 stacked notes here when everywhere else you had 3 stacks.
02:30:778 - add a bunch of notes here in a jump pattern.
02:50:547 (4,5,6,7,8,9) - not a good idea, it's very hard to read. please change it something more readable.
03:44:651 (3) - add clap
03:46:039 (3) - ^
