General
Nice spread. Would have been better if Normal was a N and Har*shot*
Add "Shalon" to tags ?
56 seconds... hum, well, try to avoid that =(
Easy
I'm not fond of these big gaps between the sliders in the beginning. Maybe you can add a few circles in there to fill in the blank ?
00:57:844 (4) - Why is this not a single circle ?
Normal
Same comment as for Easy, except more important here since the HP drain is higher.
00:57:844 (6) - Why is this not a single circle ? The slowdown actually makes it play worse than it should.
Hard
Same comment as for the other diffs...
00:57:844 (5) - Same as for Hard.
Insane
The jump in difficulty between Hard and this is too high. Try to make all the previous diffs a little harder (if possible)... And all the triples in this diff surprised me.
00:11:999 (2) - Why is there a slow down here ? The music is as fast as it was, nothing justifies it. And I personnally think it plays bad.
00:23:196 (3) - Clap ? It will be a bit more consistent with your previous clap patterns.
00:57:949 (1) - Just like the slow downs in the previous diffs, this spinner doesn't make much sense. It might also be frustrating because of how short and surprising it is.
[Shalon]'s Taiko
Pretty nice, once pattern bugged me though, because it doesn't sound like the rest at all:
00:39:675 (104,105,106,107,108) - ddkdk would sound better to me
