00:20:064 (89,90,98,99,107,108) - why lower pitch before those doublets using kats and higher pitch using dons? too weird, my suggestion is making those i selected into kats, it's different pattern with 00:13:783 - and followed the pitch
00:58:877 (285) - might wanna move this boi to 00:58:970 - it's a bit dissonant with the music as the doublet then the triplet instead of the quad like you did at 01:00:470 (295) -
01:02:439 (310,311,312) - these notes: you followed the piano before and after this, so these three shouldn't be 1/4s. maybe set on 01:02:486 - 01:02:767 - and 01:02:861 - to follow piano exactly. It's Oni so this won't meet difficult limit.
I dunno what the timestamps edward used are doing but I definitely think the notes here should be on the 1/3 snap instead of forcing the weird 1/4 snap
My vote would be to put notes on 01:02:502 - and 01:02:752 - so that it's a consistent flow through the section without any hard or unexpected changed
It wouldn't be weird in comparison to the other 1/3 section you mapped since those aren't anywhere near as sectioned off as the staggered piano in this section so the 1/4 patterning you used there still maintains the flow of the song pretty well
01:04:689 (326,327,337,338) - sudden from following the piano become into following the drums feels weird, i think maybe 1/3 for those notes are better and more consistency.
01:17:439 (399) - no likey the 1/4 positioning choice here. I think 01:17:533 (400) - would fit far better at 01:17:720 - to follow the piano like the rest of the section instead of having the 1/4 start on a note without the piano
