[Both Mr. BPChingu's Oni and Muzukashii]
i honestly have some gripes with the intro section
00:03:794 -> 00:17:911 - this works on the top diff because there's some improv alongside it but you should probably add SOME variation so it's not just kdd kdd kdd for the entire thing
00:17:029 -> 00:46:146 - from 00:46:146 onwards the improv gets alright but before that it feels very bland (and the 2 diffs even play a bit too similar imo because oni barely has any 3plets going on)
i think you should base it a bit like 01:28:499 onwards (preferably apply mods from that section beforehand though) because that section actually flows a lot more nicely compared to it
