00:52:559 (1,2,1,2) - Could do more contrast to show the large gap or it really looks like a normal 1/2 gap. Other part of the reasn being that 00:52:085 (2,3,4,1) - is actually a really linear flow and hard to distinguish in between.
01:08:506 (2,3,4,5,6,7) - don't see the need for circular flow here, especially since you used sharper flow for the kicks earlier (01:00:611 (7,8,1,2,3,4) - for example). you could redo this one part to have a bit more sharp flow
01:33:770 - Really worth mapping cuz of the uniqueness of the sound. If you didn't map it due to the stack, you could place it on the head of 01:33:139 (2) - so there's some sort of link with the previous partterning.
01:35:665 (4,5,6) - feels kinda weak when you did stuff like 01:37:875 (7,8,9,10) - . Consider making it increase in spacing.
02:01:243 (1) - the slider arrow covers pretty important sounds, you definitely could've done 4 sliders instead even though the song gets less intense, it still doesn't completely fall in intensity until 02:05:032 -
