00:56:827 (2,3,4,5,6,7) - I think you should space this stream closer together, it has a lot of notes for a [Hard] diff
01:10:194 (3,4,5,6,7) - ^
01:26:317 (1) - this?
http://puu.sh/4P2701:55:092 (1,3,5) - Add whistles here?
01:58:358 (1,3,5) - ^
02:18:766 (4,5,6,7,8) - space this stream closer?
03:03:664 (5,7,9) - Add whistles?
03:05:296 (1,2,3,4,5) - maybe remove (2)? Or, space this closer
03:08:562 (2,3,4,5,6) - Perhaps remove (3), or space this closer?
03:13:460 (2) - perhaps use soft hitsounds here?
03:13:868 (3) - Add a soft-whistle on start?~
03:16:725 (2,4,6) - Add whistles?
03:18:358 (1,2,3,4,5) - Same as 03:05:296 (1,2,3,4,5)

regenz's Insane:
03:41:827 (1) - Remove NC?
03:54:276 (1,2,3,4,5,6,7,1,2,3,4,5,6) - This pattern is odd because the spacing changes strangely, perhaps do something else here?
03:56:827 (7,8,9,10) - (nazi) 1 level 3 grid left
Nice map
