[Insane]
When I was looking through it at first, things like 00:26:119 (3,4) - confused me. Check how low the spacing is, and compare it to the rest of the begin - it doesn't really fit imo. It would be good if you increase these spacings a bit. (Just a bit, because I can see you're following a pattern which follows the background, but imo the difference is too high)
00:13:878 (1,2,3) - This doesn't really suit your style, before you used sharp curves, which causes to let things like 00:13:878 (1,2) - look really unclean. I'd try to delete those 3 sliders, and just place something else.
00:27:671 (1) - Something like

00:31:464 (3,4) - Don't stck, it's killing the needed movement.
00:58:016 (1,2,3,4,1,2,3,4) - This patterns flow is really sloppy. Try ctrl + g some of those, to create a better one.
01:19:740 (5) - 120, 196 because it's a triangle pattern which looks better than the stack. It also plays smoother to me.
02:03:878 (4) - too close to slider 3. move it a bit up
02:00:775 (3) - 20, 104, well it just looks better it's too close atm xD
02:04:108 (5,1) - Try stacking like this to improve the flow:
http://puu.sh/dpil2/835e638829.jpg02:04:223 (1,2,3) - keep same distance
02:09:280 (4) - really bad flow, it's not recommended to go in a circle here. try :
http://puu.sh/dpioS/ead3507790.jpg02:12:154 (4,5,1) - This stack doesn't play smooth either. Don't stack it like this please.
02:12:844 (2) - Stack this end with the head of 02:11:809 (3) - . Like that you can create a progressing curve.
http://puu.sh/dpiuC/99c3f32255.jpg02:16:292 (4) - stack with head of 2
02:24:568 (4) - same
02:30:430 (1,2,3,4) - don't put them centre-aligned, make something which is not so straight, straight finish off is so boring..
good luck kazua :3
