00:15:571 (1) - Ending this at 00:16:977 would sound better than where it does now for two reasons: For one, it sounds better ending on some vocals rather than on some less significant sound, and secondly it would have a 2/4 gap between it and 00:17:446 (1) - which sounds nice because the sliders after it are also 2/4 apart
00:21:196 (5,6,7,8) - Separate these from 00:17:446 (1,2,3,4) - to add a bit more movement, at the moment it feels a bit too plain. The buildup at 01:58:696 (1) - is nicer than this one imo, so maybe do something like that if not the first suggestion
00:30:571 (1) - You could stack this with 00:32:446 (1) - like you've done with 00:32:446 (1) - and 01:04:321 (1) - , 01:06:196 (1) - and 01:08:071 (1) -
01:54:125 (4) - this slider is a bit confusing, i think this slider should start 01:54:008 - here and end at 01:54:477 - here to cover the vocal
02:13:696 (1,2,3,4,5,6,7,8,9,1,2,3,4,5,6,7,8,1,2,3,4,5,6,7,8,9,1,2,3,4,1,2,3,1,2,3,4,5,6,7,8,1,2,3,4,5,6,7,8,1,2,3,4,5,6,7,8,1,2,3,4,5,6,7,8,1,2,3,4,5,6,7,8,9,1,2,3,4,5,6,7,8,1,2,3,4,5,6,7,8,9,10,1) - clockwiseclockwiseclockwiseclockwise you should change it up a little
02:54:946 (1,2,3,4,5,1,2,1,2,3) - these dont play very well, i suggest turning them into http://cute.lazer.moe/kZvsels.png 's
03:12:758 (1,2,3,4,1,2,3,4,1) - 01:01:391 (3,4,5,6,7,1,2,3,4,1) - 01:09:946 (1,2,3,4,5,6,7,8) - 02:10:883 (1,2,3,4,5,6,7,8) - If this diff it s supposed to be an hard, "Avoid streams made of more than 5 notes. " Overall i would avoid at all streams on the intense parts and do 4 notes streams+reverse slider for the rest
