00:21:532 (3) - unrankable slider, you can't tell where it goes when you play this first time
You should focus more on aesthetics and flow of your map because it's pretty random.
For example this 00:44:040 (3,4) - this overlap looks pretty bad, if you will move one slider to the other place i will look better, also you don't keep the angles of the sliders, these two sliders 00:44:040 (3,7) - are very close on timeline and they are slightly different.
Jumps are also kinda random and don't have good flow, some of them hav it and some not and this makes your map inconsistent and uncomfortable to play. Wide angles like this 00:43:707 (1,2,3) - are very bad for flow, especially when previous jumps look like this 00:43:040 (1,2,3).
Your spacing is very inconsistent and incoherent to the music. In this section 00:42:207 (1,2,3,1,2,3,1,2,3,1,2,3,4) - your spacing is totally random. You start with stacked pattern 00:42:040 (3,1), you continue this here 00:42:540 (2,3) and all of the sudden you change it to high spacing jumps 00:43:040 (1,2,3) and again jumps 00:43:707 (1,2,3). It wouldn't be bad if not the music. You mapped to the vocals, but vocals goes like LOUD-silent-LOUD-silent so you should do something like JUMPS-stacked-JUMPS-stacked.
00:14:207 (1,2,3,4,1,2,3,4) - your jumps are pretty random, try to use the same angles for some of them and don't make the first jump with that wide angle 00:13:873 (2,1,2)
00:07:540 (4,5,6,7,8) - fix rhythm here if you want to map to vocal (make something like this https://i.imgur.com/lYRIIyC.png )
in whole diff you have sections like this 00:04:873 (3,4,5) - 00:16:707 (5,6,7) - try to copy all sliders and use only one slider shape for them, and also fix overlap on 00:16:707 (5,7)
01:07:679 (1,1) - i don't think it's a good idea to stack these two objects cuz it's hard to see this stack and players will think it's continuing the rhythm of the burst
in this section you can do something like this, it will fit the vocals better https://i.imgur.com/N6OFuOC.png (cursor on 01:31:010)
