00:02:163 (1) - I understand there's a sound on the red tick, but I think the vocals are so strong that it makes this repeat slider feel weird. Also the white tick has a strong vocal sound, so it'd be best to put a circle here or one slider that doesn't repeat and ends on that tick.
00:02:718 (2) - I don't think this should be here, but that's just me
00:02:903 (3) - There's some nice vocal sounds in here that you just ignore, but I think they could be mapped
00:03:644 (1,2,3,4) - Consistent spacing, I also think these could be spaced more. Back and forth would work well here imo
00:05:125 (1) - Incorrect rhythm I think. Slider should extend to blue tick so it ends on red tick later
00:05:866 (2) - I think this should extend to blue tick as well? idk
00:07:162 (3,1,2,3) - The rhythm is completely wrong here. The white tick that 3 ends on is a strong sound, so you should consider something else to have a NC here. Also the rhythm of that part isn't really a triple, it's more like this:
https://puu.sh/tq4GY/560d50f369.png00:08:274 (5,1,2) - This is an odd flow of direction, but if you keep it consistent that's kinda ok
00:09:570 (1,2,3,4) - You have better spacing here, but still should be higher spaced imo
00:11:051 (1,2,1) - More flow stuff. This and the previous flow thing can be summed up as: sliderends should point towards the direction of flow
00:12:533 (1,2,3,4,5) - This is also a part with poor flow, the zig-zag at the edge going in that direction is very awkward to play
00:13:459 (1,1,1,1,1,1) - Not sure the NC on every note is necessary, but it is pretty cool and might be fitting... your call
00:14:014 (1,1) - No need for NC here
00:14:014 (1,1,2,3) - Try to keep a consistent pattern, you have one spacing and direction that just changes completely without a change in the song to back it up
00:15:496 (4) - The placement and direction of this is strange. It might also help to make these sliders curved instead of straight, but that's another call for you to make. As long as it's consistent
00:16:607 (2,3,4,5) - Good use of spacing to show the change in the song, maybe consider making NC between 3 and 4, as well as making them go in opposite directions
00:18:459 (1,2,3,4) - Spacing could increase here as well
00:19:940 (1,2,3,4,5,6,7,8) - There are a lot of ways you can make this rhythm more playable. Even if you want to keep the squares, try to make it consistent with for instance distance snap, cuz they're not very clean
00:21:422 (1,1,2,3) - I think this would work better:

I recommend watching a lot of pishifat's videos, they're insanely helpful.
