00:22:220 (5) - How about changing this to a circle to distinguish the vocal from 00:21:596 (3,4)?
00:34:361 (3,4) - I think this rythme is better, because this is more natural to play and there are fewer clickable notes in this part, so I don't think it's a problem in terms of density.
00:39:025 (2,3,4,5,6,7) - It is understandable that the song is expressing the excitement of the song, but this pattern is too difficult for this part. 00:39:335 (4) - what about changing the - to 1/2 slider to reduce the density
00:44:295 (4,5) - This vocal set is stronger than 00:43:984 (2,3), so unstacking 00:44:295 (4,5) would help differentiate the vocal intensity.
ds is fine, i think the stacking leniency is what make it look like they close to each other
01:12:136 (4,5,1) - would be better for emphasis reasons if you didnt map the triple in here. not only do you not map the other triples in this section (01:13:447 - 01:14:689 - 01:17:176 - etc), removing the triple will signify a change in intensity from the very intense chorus to a weak downtime
01:43:996 (4) - i think this shoudn't be reverse, 01:44:307 - I feel like it's a huge waste of time to use slidertail to describe the snare of the So why not try 1/2 slider + circle?
02:12:912 (3,1,2) - this rhythm makes no sense, the 1/2 sliders should be starting on 02:13:222.
02:51:382 (5) - 02:53:869 (5) - the triples in this section should be hitsounded on your difficulty if you plan to overmap them
