Looks pretty good. I dunno about timings, but I got 300's on most notes on Normal (100's due to my tiredness right now).
Normal
Really like your use of spinner+break. =]
00:54:12 (1) - End this spinner at 00:55:73 (1/2 back). Remember to readjust the break.
01:27:35 (1) - Like above, end at 01:28:97 (1/2 back).
01:59:66 (3,4,5) - A big suggestive. ;P Make the slider point down instead of up, and vertically center it with the two hit circles.
01:58:97 (1,2) - Add a hit circle 1/4 before each of these, stacked.
02:41:20 (1) - Like first two suggestions. End this one at 02:42:81 (1/2 back).
02:55:97 (1) - Like above, end at 02:57:58 (1/2 back).
Insane
Beginning could be worked on. Looks pretty much identical to Normal.
00:31:97 (1) - Split into lyrical melody.
00:39:35 (1) - Same.
00:54:23 (2) - Remove.
00:55:97 (x) - Remove and re-insert the break here.
01:05:20 (1) - Split into lyrical melody.
01:12:58 (1) - Same.
01:27:47 (2) - Remove.
01:29:20 (x) - Remove and re-insert the break here.
02:21:58 (5,6,7) - Convert into a repeating slider, perhaps?
02:28:97 (5,6,7) - Same as above, but less likely. If you do the above, probably don't do this.
02:58:04 (x) - It'd be cool if this part were mapped ("lie lie lie lie-lie-lie...") but there's no nice places to stop after this (I think) to have a satisfying end.
