Yo, I freaking love this song.
I'll start with Insane because I usually tend to put the most effort into the first diff I mod.
-Insane-
Woah woah dial down the HP drain a little.
00:20:891 (1,2,3,4,5,6,7,8,9,10) - Add a slider repeat to (9) and (10) and then rearrange the stream like this:
http://osu.ppy.sh/ss/175859 In my opinion it looks and flows better.
00:31:925 (1,2,3,4,5,1,2,3,4) - Perhaps rearrange the hitcircles so that the stream is more circular? Idk it looks messy how you've done it. Could you you do this for all the streams that look like this please?
00:35:718 (5,6,7) - Stack on the endpoint of (4)?
00:55:287 (10) - Remove this slider repeat.
00:55:373 (1) - Delete this note.
01:11:236 (1,2,3) - Stack with the start point of (4).
01:33:649 (4) - Whistle (Endpoint only).
01:39:167 (4) - Whistle.
01:44:339 (3) - Whistle.
01:47:787 (1) - Whistle.
01:47:787 (1,2,3,4) - These big jumps seem kinda sudden, perhaps make them a little smaller than the jumps at the end of the 2nd kiai.
02:02:529 (5,6) - Stack these with the endpoint of (4) like you have with many previous patterns. Plus, it doesn't looks very good like this. You may have to reposition (7) if you make this edit.
02:24:684 (3,4) - Turn this into a 3 hitcircle stack? I generally dislike patterns like this.
02:28:477 (1,2,3) - Stack with the start point of (4)?
02:39:856 (5) - Whistle (Startpoint only).
02:42:098 (3) - Stack with (2).
02:45:373 (7) - Whistle.
02:50:546 (4) - Whistle.
02:50:891 (7) - Whistle.
02:53:994 (1) - Whsitle.
Nice diff.
-Hard-
AR 8 seems kinda high for a Hard.
01:40:029 (3) - Delete this note.
02:08:477 (1,2,3,4,5,6) - Perhaps turn this into a slider pattern of some sort? This doesnt look too good.
Umm... ok not too many errors there... O.o
-Normal-
AR 6 seems a little high for Normal.
I always suggest that a map's easiest diff uses circle size 3.
00:38:649 (2) - Move back to the red tick and extend by 2 ticks.
00:49:856 (2) - ^
00:55:029 (4,5) -

01:11:925 (2) - Move back to the red tick and extend by 2 ticks.
01:22:960 (2) - ^
01:25:718 (1) - 4 grids down.
02:18:132 (2) - Move back to the red tick and extend by 2 ticks.
02:26:753 (2) - Delete this note? Idk...
02:29:167 (2) - Move back to the red tick and extend by 2 ticks.
Nice mapset, would like to see this ranked.
Take a star!
