[general]
personally I would have used one background and used storyboard to put in the difficulty names.
[Normal]
00:21:059 (1,2,3) - can you use copy/paste and rotate by on these? Other ones too (eg 00:28:559 (1,2)). It makes the map look a lot more polished
00:30:902 (2,3,1,2) -
http://osu.ppy.sh/ss/202354 just a little cleanup. I think overlapping sliders should be avoided if possible, and you should try for symmetry as well.
00:53:871 (2) - the beat is dropped here, maybe you could do something a little different rhythmically?
[hyper]
01:17:309 (1,2) - finishes? you didn't do normal hitsounds in any of the others, I suppose this is part is part of the style differences?
01:33:598 - clap
01:33:949 - clap
01:36:996 (2,3,4,5) - can you take off grid snap for these compressed streams so that the spacing is constant?
[another]
00:02:543 (8) - This note's pitch is a 5th above the previous note. In music, that's a pretty substantial jump in pitch, and it would be cool if the beatmap reflected that.
00:07:934 (1) - can you take the whistle off the notes here except on the white ticks? The blue tick is noticeably softer in the music, and the difference between soft-hitnormal ad soft-hitwhistle is perfect to show that.
00:13:559 (1,2,3,4) - It's not quite perfect-looking, but I suppose there's little you can do.
00:48:246 (5) - I think if you delete this note in each new combo, the pattern here makes a lot more sense. You did that in the later section and I found it much easier to follow.
01:07:934 (1,2) - can you make this a slider? The main part you're mapping has just 1 note here, and you only have to hit sliders once.
01:17:309 (1,2,3,4) - normal-hitfinish sounds much better for these 4 beats.
