General
Turn of letterboxes in diffs, because you have a video~
1st and 2nd combocolours looks close, make a bigger difference, if you can orz
Normal
Okay, there is a big gap between diffs, but nah, it's fine.
Normal diff seems too hard for me : AR4, OD2 have more sense than AR5, OD3, cuz it's an easiest diff. Also diff will have less than 3 stars.
01:17:110 (3,4) - increase spacing a bit?
01:38:539 - inis break? hum, usually it should be snapped on white tick. and HP2 is not HP8. just remove this short break, looks better without
01:41:253 (2,3) - stack with SL 0, you know about this rule, right?
02:06:539 (2,1) - could you avoid this overlap?
02:48:110 (4,1) - stack better or unstack
Hard
01:21:967 (7) - x:72, y:192 (half grid to the left)
01:32:539 (5) - add nc here? new vocal part
01:34:396 (1) - vocal part is still here, remove nc
01:35:682 (2) - add nc here, new vocal part
01:39:825 (3) - big distance between, add nc
01:48:110 (1,2) - unstack, same reason as in Normal
02:16:825 (4,5) - you can stack it better, i know it
02:37:682 (1,2,3,4) - awwww --^
