Hi, just coming back with a few suggestions.
[
Kantan]
00:10:321 (14,15) - A break here would help to separate both sections in the music better, same in 00:44:666 -
[
Futsuu]
00:10:321 (23,24) - Something similar here, also I think this would make the big kat play better. Same for the next part.
00:18:597 - A note would be nice to put here, so the spread for Kantan-Futsuu-Muzukashii improves. A kat would make a good play for the lyrics; a don would be the best option for the instrumentals, if you do the latter, try changing 00:19:011 (43) - to a kat, however, this colour change is optional. Same for 00:21:907 - , 00:25:218 - , etc.
[
Muzukashii]
00:09:907 (30,31,32,33) - Not following the 3/4 here?
00:27:907 (103) - Remove it so you have consistency with previous patterns?
00:29:149 (108) - Remove to make it less like Oni?
00:30:804 (116) - ^
00:36:390 (137,138,139) - I think a simple kat (resulting pattern: d k d k k) would make a nice pattern variation instead this triple.
In case you apply something here, remember to apply these to the next section

Oni]
I see you deleted a few notes here. It wasn't really needed, but okay.
00:09:907 (41,42,43) - No 3/4?
00:19:632 - How about a note here, this beat feels a bit empty. Same for 00:21:287 - , 00:26:252 - , etc.
Inner Oni is good.
No kds.
