00:00:139 (1,1,2,1,2,1,2,1,2,3,1,2,1,2,3,4,1) - excessive use of NC when there isn't any notable change in the rhythm. It's recommended to put NC around every 2 downbeats so as to follow the vocal's pace
for example:
00:26:409 (1,2) - Similar visual spacing with 00:29:809 (1,2) - but have different beat snapping gap. You get the idea already
00:33:493 (1,1,2,1) - the general movement of these objects are pretty awkward to play.
ctrl+g 00:33:776 (1) - could make the aim from 00:33:493 (1,1) - much more fluid and you could put 1/2 slider here 00:34:059 - (considering it's also a rather impactful transition) rather than just a circle so you put continuous movement from 00:34:059 - to this slider 00:34:342 (1) - and the overall gameplay could be smoother.
01:07:165 (1,2) - The sound that only indicate stop-and-go emphasis are vocal here, but you follow drum here 01:06:053 (1,2,3,1) - . Better unstack it to follow the general emphasis of the instrument
and once only you put 1/1 stack here in the whole chorus section without any notable rhythm change. pretty weird if you ask me.
01:22:193 (4) - this active object doesn't reflect any prominent sound in the song, and since you ignored kick at 01:22:335 - the emphasis become more questionable. Just delete the circle and prolong 01:21:767 - by 1/2 and you can complement the guitar sound more.
01:23:330 - delete slider and add 1 circle here instead. all of the object (included passive) here 01:23:046 (1,1,1,2,1) - follow every sound except here 01:23:520 - so having hold note there kinda blurred your emphasis
01:23:615 (1,2) - having kick clickable while the snare became passive is weird, especially in hard diff when you still have to simplify rhythm to an extent. quick solution would be making 2 1/2 sliders (without reverse) so each slider would follow clap and kick respectively
