00:08:378 - could map this for the snare (if the concern is that it makes a 6-plet, i would delete 00:09:578 (13) to fix that, otherwise i think a 6-plet on low bpm is fine)
same with 00:11:578
00:12:278 (18) - i would delete this since this a bit complex for a kantan. also why isnt 00:11:978 (17) a finisher? its the same as 00:12:578
delete 00:19:378 (32) for similar reason too. (same thing about the finisher with 00:19:078 (31)
I definitely agree with the finisher part, but the pattern itself is pretty much BPM200 1/1, which is not that far off from BPM180 1/1 (what the RC uses), so I personally wouldn't worry that much.
I'd personally delete 00:18:778 - instead, since it would make the gap from 00:18:378 - the same as 00:13:578 - & 00:15:178 - , and would indicate a clear separation from normal notes with the finisher notes
00:21:878 (35) - is this a mis-snap? no clue why its 1/4 here when the melody is on the white tick
00:25:978 (42,43) - i would actually make the first note a regular one and the second a finisher instead. the 2nd note is more impactful that way
same with 01:04:378 (113,114)
00:50:678 (86) - same thing i said earlier about this being complex. (could finisher 00:50:378 (85) as well)
00:57:378 (99) - move this 1/4 forward, its mis-snapped. would also delete 00:57:778 (100) to simplify the rhythm
i would also delete 00:58:378 (102) so the melody stays prioritized, not as problematic as the first point tho
