00:35:065 (4,1) - This pattern might confuse newer players bc of how visually similar it is to 1/2 stacks like 00:34:449 (1,2) right before. I'd unstack it
00:23:219 (1,1) - only a 1/2 of a beat might not be enough time for players to react after the spinner. Don't know how strict this is, but going by the ranking guidelines there should be at least one whole beat between a spinner and the next object
04:16:218 (1) - took me a while to figure out what you're following here. I'd definitely prioritize the vocals/drums as they are much more prominent. The player will barely even be able to hear those quiet guitar sounds.
This applies to the enitre section. Rhythmically, it feels off right now
04:03:336 - add a finish to the spinner's end? Since there's a cymbal. There are also other cymbal sounds that you ignored, I'm not sure if it was on purpose or not, but I'll put them here just in case.
02:42:865 (5) - 02:47:100 (4) - 02:54:336 (1) - 04:14:630 (1,2) - 04:49:041 (2)
It's not a repetition really, 3 is a "da" vocal and 4 is "na" and belongs to the next word already ("nanda" https://www.animesonglyrics.com/houkago-shounen-hanako-kun/koi-koi-koi)
Tried doing it where it made sense to me, but left it for stuff like 00:15:153 (3,4,5) since the drums go a bit ham here.
Along with the other suggestion Tesla made I think the contrast between kiai and the rest of the map is definitely better now
