Okay, timing seems right to me as of now. First thing that came up was that I really dislike was the string of beats from 00:23:04 to 00:24:59 in Insane... Seems like you just decided to throw in a bunch of random beats there in a messy string. XD
Spacing is nice and consistent enough. I personally know I can't beat Insane (my Osu! skills aren't that good), but it might be a bit easier if you pull the spacing together a bit tighter. That's absolutely based on personal preferences though. So, it is your choice whether you want to do that or not.
I am happy with this other than the messy string on that part, so... *star*
