I didn't find anything about this song in the web,are you sure about title/source? could you give me some links?
[Easy]
00:17:375 - hitsounds are so rough..why not to use soft sampleset here? and you could add whistles then,because half of a map doesn't have any hitsounds
01:25:460 - I think note is missing here
01:36:524 (4) - add another repeat?
[Normal]
00:17:375 - use soft sampleset?
[L i a's Hard]
00:02:056 (1,1) - looks really werid,though it makes sense,but I'd suggest to remove second combo mark
00:15:779 (1) - this spinner wasn't expected much at all,start it from 00:14:822 if you want to keep it
00:16:949 - well,hitsounds sound better then in other diffs,but I can hardly hear them,so raise volume to 40% or make a soft sampleset with 50% or more
01:13:332 (11,1) - werid spacing,I'd suggest not to jump here
01:23:758 (1) - again,start spinner from 01:23:013 or map something instead of it
01:37:375 (3,4) - plays little awkward,why not to add 2 repeats to (3)-slider?
[Insane]
00:54:290 - no no,you can't silence notes
that's it,awesome song btw
