00:01:299 (2,3,4) - there's an unnecessary gap here with 2.5x spacing which isn't looking fine for cup so how about you move the sliderend closer to (4) note, or move the anchor around x:330 and then make a 1.5x DS walk?
00:09:266 (2) - here probably the same but the anchor this time is a sliderbody aka the middle of the slider, move closer to the right until the snap changes
00:05:299 (1,2,3) - 00:21:234 (1,2,3) - etc. could probably be made into full sliders rather than reverse. this clears some density and follows the guitars just the same.
