During 01:09:006 - 01:26:148 - as you are not following the vocals in this section, I would advise placing whistles on the exact sounds you are following. Keep in mind that hitsounds may work differently for different difficulties, so it would be beneficial to adapt them accordingly to suit each difficulty.
个人觉得比起单个circle，用急促结束的1/8滑条（尾巴5%音量消音）更加贴合这部分的这两个音，要不要试试？
01:11:708 (2,3) -
01:20:280 (2,3) -
01:44:377 (1) - I do think it would be good to somehow highlight the vocal here, perhaps by changing up the jump's angle. This applies to all jumps like this (01:48:662 (1) - 01:52:948 (1) - etc)
The second kiai feels a bit bland to me right now since you're almost only following the instruments, even though the vocals are also very interesting
I think I cannot do that since, from my perspective, 01:43:841 - has no vocal so It's the only place I could do some change to reflect the vocal but there are also snare and some squishing instrument (idk what that is) so it's intensity does not change, which makes changing something here pretty weird. On the other hand, 01:49:734 (1,2,1,2,1,2,1) - etc is expressing the vocal change so I think that would be enough.
I recommend adding some additional feedback by using soft-whistles to emphasize the additive rhythms. I suggest reviewing the entire map and including whistles in places like 00:36:193 (2), 00:38:336 (2), 00:40:345 (2,3,4), 00:42:488 (2,3,1), and so on.
Added on 1/4 additives. I don't think things like 00:40:345 (2) - need it though, it doesn't quite stand out.
