[Kantan, Futsuu, Muzukashii]
01:15:478 (1) - Would be nice if this was a big note. It's still rather powerful (end of kiai) and marks the end nicely as well, in my opinion at least. Technically works for Oni too but please don't do that it wouldn't be good (I doubt you would anyway)
[Kantan]
Honestly think that several spots could have more notes as 2/1 notes are almost 2 second breaks. 00:25:764 - 00:39:478 - come to mind.
00:54:049 - 01:07:764 - these two spots might be nice additions as well, because the Kantan feels very underwhelming compared to Futsuu, which has 1/2 5-plets at its hardest spots, while the kantan has 1/1 triplets at most.
[Muzukashii]
00:59:621 (28,29,30,31) - Why not 1/4 doublets to follow vocals? Only pointing this out here as it's more than in the other 1/4 doublet spots.
01:08:193 (15,16,17) - 01:14:192 (28,29,30) - sure you wanna keep oox 1/4? Before the kiai Muzukashii already is quite technical compared to Futsuu because of the 1/4 doublets. Especially the second worries me because it's surrounded by 1/2. So either change both to monocolor or remove 01:13:335 (26) - OR 01:15:049 (31) - (deleting first one doesn't sound that bad imo)
[Oni]
00:11:192 (16) - why isn't this a kat? The other 1/4 triplets here didn't follow the pitch either. (And to be honest the guitar rather goes dkd)
00:27:157 (41) - 00:40:871 (43) - imo it's cooler when the 1/8 only appears in kiai to emphasize that it's the strongest part of the song. Outside it seems rather unfitting.
call me back hope this can be ranked in November still
