00:17:905 (3) - Slider may be a little tricky, considering the previous slider only had one reverse arrow. Taking this into account, and the strong vocals landing on 00:18:245 - , I'd recommend removing one reverse arrow and add a circle there.
As it may also affect your visuals a bit, thinking the below would look neat?
00:27:336 (1) - Remove the combo here and add a new combo to 00:27:677 (2) - . That'll follow the same thing as done previously at 00:06:995 (3,4,1) -
00:56:541 (1,2) - I recommend keeping the same rhythm choice as done previously on 00:41:995 (1,2) - . The vocals are strong enough to keep that rhythm flow going, and that's just gonna make it easier to identify as well.
