00:21:272 (5,12) - I'd suggest putting these notes on the following blue tick, and deleting 00:22:100 (8) - . It will fit better with the vocals and not be too hard. (If you do this maybe put this one as a kat 00:22:307 (8) - )
00:39:894 (25) - This note feels a bit ff in the muzu, deleting it will be better, also considering that you didnt put one at 00:41:549 - .
00:49:824 (25) - Delete this one ? There is no note at 00:48:996 - so it feels weird to hear.
In the kiai : Avoid using 2 triplets in the same pattern like 00:57:065 (14,15,16,17,18,19,20,21,22) - , or 01:01:410 (35,36,37,38,39,40,41,42,43,44,45) - if you want to keep the pattern, kill one of the triplets.
00:41:032 - Maybe add a kat here to emphasize a bit the measure
00:41:549 (43) - Putting this as a kat could help reading a bit and flow better
01:03:272 (61,62,63,64,65,66,67) - What about ? It will flow and emphasize better.
01:19:512 (29) - I think you can remove this note for a little break, there is a lot of 1/4 in this part and this note isn't really necessary
