Raise AR to 3
00:15:388 (1,2) - Blanket?
00:35:230 (3,4) - Break the flow imo. Plus it might mislead beginners to click on 4's end instead of its start
00:50:348 (1,2) - How about this:
01:43:262 (2,3) - I feel those two sliders' shapes should be interverted for a better flow:
01:53:655 (1,2) - Like earlier, broken flow
01:58:380 (1,2) - It doesn't look too bad but I'd avoid overlaping if possible
02:35:703 (1) - How about putting one more red anchor here 02:36:411 - to emphasize the beat?
02:56:962 (3,4) - Blanket?
02:59:797 (2,1) - ^
03:02:632 (2,1) - Like earlier, doesn't look bad but I'd avoid overlaps
Also, redo your NCs, they should be more consistent. Just place 1 NC every measure for dynamic parts with lots of objects and 1 NC every two measures for more chill parts.
