00:04:959 (1,2,3,4,5,6,7,8,1,2,3,4) - move these a little bit further down to avoid stack with 00:04:185 (5) - and 00:04:959 (1) -
00:20:830 (2) - Current rhythm feels a bit underwhelming for that sound. It would be better if you map both slider tail and head as circle because it's more better to cover the high pitch sound as you did at 00:21:217 (3,4) - 00:27:024 (3,4) -
00:21:217 (3) - This rhythm is a bit underwhelming for such high pitched prominent sound. It would be more intuitive to mapped it as circle like you did on 00:27:411 (5,6) -
00:42:024 (8) - It would be more intuitive to delete this note and more focused on cymbal sound at 00:42:121 (1) - because it's more prominent from the rest of that section.
00:51:024 (6) - Lower this spacing would better here to make more speed 00:51:217 (7,8,1) - and to emphasize the vocal on 00:51:411 (1) -
Something like (https://osu.ppy.sh/ss/14046853/1f72) would work or something that you preferred.
00:53:540 (1,2) - this spacing for vocal sound is pretty same with instrument spacing 00:53:153 (2,3) - which make the emphasize on 00:53:540 (1,2) - feels flat. It would be better to increase the spacing a bit so they are not same with instrument spacing on 00:53:153 (2,3) - .
Also make sure to make a spacing build up since the vocal pitch gradually increased on 00:53:927 (1,2) -
01:00:701 (1,2,3) - add more spacing here to differ each vocal section in that part like I said on #1240048
01:01:669 (7,8) - Ctrl + G this rhythm would work to emphasize vocal and be more consistent on how you follow vocal on previous part 01:00:701 (1,2,3,4,5,6,7) - (https://imgur.com/kuWwjBd)
01:05:830 - 01:06:024 - It would be make sense if you fill this gap with circle to consist with your rhythm choice on 01:06:121 (1,2,3,4,1,2,3,4) -
Also this 01:05:540 (3) - slider tail has a important beat to map and make it passively played is a bit underwhelming. Something like this (https://imgur.com/0gqMzal) would work
