Oh god, this, I don't even...
Anyway I've seen taiko mod request (do you also need osu!standard mod? if so PM me in-game/forum) and I'm gonna do some, even though I'm still new to taiko modding thing.
[Muzukashii]
00:46:994 (25,26,27) - ddk? the kdk pattern is in my opinion overused, and ddk would fit here because of no vocal being here, as opposed to kdk before.
01:03:129 (79,80,81) - ^
01:09:179 (99,100,101,102,103,104) - For me KK DD KK doesn't feel right here, because of the repeating of the word in lyrics she is singing, I think a KD KD KD would be easier, and nicer for this part.
02:17:750 (286,287,288,289,290,291) - Same as the previous, but more like DK DK DK because of the pattern before used (one d, and before there was 2 d's)
01:15:733 (124,125,126) - why using dons for clap? maybe k k k ?
01:15:733 (124,125,126,127,128,129,130,131,132,133,134,135,136,137,138,139,140,141,142,143,144,145,146,147) - the whole part, it's a slow part, i know, but not using kats for claps, seems wrong for me (especially, when there is ONLY claps for example like above)
02:23:044 (303,304,305,306) - kdk k? I think it would fit - both claps in music, and the singing.
Oh god, let's hope that wasn't shit mod

01:18:254 (171,172) - Isn't it a little bit undermapped? It's pretty the same as in Muzukashii, but oni is supposed to be harder right? Even putting dons on red lines makes it alot better IMO.
Also, as in Muzukashii, but here is even more weird - because claps are followed partially, I know it's not like osu!standard, where hitsounding isn't not followed 1:1, but even though, I find it strange (that's still just a opinion).
Since I'm not very good at taiko, I don't find any patterns weird here, except said before.
