00:02:169 (5) - Maybe just use a hitcircle here instead to introduce a 1/2 gap like you did at 00:07:386 (5,6) - and also to decrease rhythm density for this calm part.
00:38:202 (4) - Could make this a 1/2 slider instead for the sound on 00:38:365 - ?
Would be nice since the sound here is different compared to 00:33:147, maybe try something like this:
00:48:799 (1,2,3) - Would increase spacing for the 1/2 here since it looks so similar to your 1/4 spacing, alternatively could just NC to differentiate.
01:10:810 (6), 01:59:560 (2), 03:49:125 (2), 04:09:995 (2) - NC to signal the 1/2 break?
02:02:169 (3,4) - Might consider ctrl+g'ing this to attach the synth of 02:02:332 - in a similar way as you did 02:00:865 (2,3,4) - with these
tho if you really wanna keep the snare at 02:02:495 (4) - as a clickable it's understandable
02:22:386 (4,5) and 02:38:691 (6,7) - High spacing here feels pretty out of place in this calm section since they're not emphasizing much, would reduce a bit.
02:52:712 (1,2,3,4,5), 02:55:321 (1,2,3,4), 02:57:930 (1,2,3,4) - Could be cool to use SV changes here for the decreasing pitch here. Maybe try something like 1.3x > 1.2x 1.1x > 1x?
