Overall:
empty osb i mean how can you leave that thing in there- ooompfh i'm sorry master please don't hit me again ;_;
Insane:
ilu
Hard:
00:17:164 - 00:30:878 - I find the finish sounds you're using here a bit too heavy-sounding while that part is actually relatively calm compared to the rest of the song. In Insane, whistles were used on those hitfinishes to make them sound a bit less harsh. Maybe do that too?
Normal:
HPDrain and OD could be increased a bit if you like. By one tick each perhaps?
Easy:
00:55:092 (1,1) - A bit harsh on an Easy diff that you have an object so soon after a spinner. Consider changing that, please!
01:10:307 - supershort breaks like those usually suck imho, and here's no exception
Do as you please though, it's rankable and probably really subjective anyways. Though you don't really need one there; the HPDrain is low enough to not matter there.
01:51:450 - ^
Well done mapset, good difficulty spread and few errors!
