Easy-
00:15:362 (2) - Is this sliderwhistle on purpose? If it is, it sounds horrible so remove it :>
00:34:186 (2) - ^
00:45:950 (2) - I'm going to go on ahead and think that the change on the sliderslide is not on purpose. Remove 00:46:391 timing section.
01:30:656 (2) - Not perfectly symmetric, Look at the middle point :> (use grid lvl 4 for this one) (and also yes, I notice this stuff while playing)
01:40:067 (2) - ^uguu (same for the other copy-pastes)
01:44:185 (1) - Don't you think normal hitsounds sound better here?
01:54:773 - Remove this timing section to avoid the sliderslide sound change
03:32:126 (1) - Forgot to add a finish like in the other diffs
Hard-
(Yes, I don't mod them in order, boo hoo)
High OD doesn't fit the diff imo, reduce by 1 or 2?
01:44:185 (3) - Same as easy?
00:57:126 (1) - All these sliders are not perfectly symmetric but I'm being so nazi I would kill myself over it :> (btw, if you want to fix dem, grid lvl 4 and move the control points before and after the red points to the middle, 100% you won't but ~~~~)
Normal-
00:38:303 (3) - Is this sliderslide hitsound change in purpose?
01:44:185 (2) - Same as dem other 2 diffs.
02:41:538 (2) - Finish at the end is totally anticlimatic (and this is the only diff on where you have a finish at that time)
02:46:244 (2) - ^
02:54:773 (1) - What's with the sliderslide change just before the repeat? sounds bad. Make this slider like the one you have on easy or remove those timing sections at 02:55:215 - and 02:55:362 -
That'd be all (no, I didn't check general aspects, sue me :>)
