00:19:800 - what is this following?
00:19:950 - this triplet is on drum, then 00:20:250 you made a break here leaving white tick to switch to follow vocal for 4 notes, which is very awkward, and doesnt sound right, given the fact that the 1/1s at 00:21:300 is not on vocal at all so what prompted the change?
since the section is full on 1/4 drums i'd say go for consistent triplet pattern like below, would play better
01:40:330 - i think this have same situation with #4703236/12779852 since you're applying it on top diff then should apply to this diff too for better spread
01:45:130 - 01:45:430 - 01:46:930 - 01:47:530 - 01:47:680 - 01:47:830 - this following notes could be removed to match the density of intro section 00:01:780 - since they're musically same, reason i also suggested to remove 01:47:680 - is because to reflect the absence of the drum kick which would contrast with the intensity better
reason im not suggesting ooo o o ooo o
is because the drums is slightly different with 1st kiai verse
