00:03:533 00:09:180 - i don't think the intro density needs to be that low, can consider adding notes here. the contrast would still be there with the frequent 4/1 breaks

00:23:650 you could map this since you only need a 3/1 for rest moments

00:25:415 (33,34,35) - 00:28:239 (38,39,40) - these are the places where the song really builds up as it goes up, but 00:24:710 (31,32) - 00:27:533 (36,37) - is more dense? Just seemed a little flipped around

00:31:414 - adding a note here for the vocal would make this pattern sound nicer

00:33:891 - missed finisher? you usually use them on intense sounds or on cymbals, so its odd to not finisher this. same with 00:36:714, 01:02:126, 01:24:714, 01:27:538

00:36:357 - very optional but changing to k for kkD would be nicer to play and fits the vocal pitch imo

00:43:414 - would map this vocal so its consistent with 00:40:591 & 00:42:002

same with 00:46:238 & 00:49:061 and etc. (also applies to the later kiais)

00:45:355 (69) - i get that this is for the vocal, but i would move this 1/2 back so its aligned with the cymbal (you can also make it a finisher by doing this)

same with 00:56:649 (91) (also applies to the later kiais)

00:47:298 - can change to kdk to avoid repetition from 00:41:651 since these timestamps sound pretty different

01:06:355 (106,107,108) - make these mono-colored since the vocal is repeating the same words, would be a better way to represent it

same applies to 01:12:002 (115,116,117)

01:07:767 --> 01:09:179 - the current structure doesn't really reflect the song that well so i would suggest either doing x xxx or --xxxx

01:13:769 (115) - I get that this is where the vocal starts but leaving out 01:13:416 seems odd and goes against what was established at 01:07:769

01:14:120 - this just sounds odd to omit this + you dont break any rest moment guidelines by mapping this

01:57:538 (199) - would actually suggest moving this to 01:56:832 - to reflect the kiai progression better and for a nice 7-plet

you can also do with with 02:01:420 --> 02:02:832 and the others

02:06:357 - changing to sth like kkddkdk would be pretty neat for variation from 01:55:062

02:15:714 This note feels like it should be 1 tick earlier

02:19:768 - 02:20:474 The last three notes can be made finishers, a solution you have used in other diffs, I think in Kantan it is also appropriate
