02:51:238 (1,2,3,4) - this part makes me itch so bad, its a big break from the distance snapped patterns you've done in many other parts very similar to this and making it a rectangle breaks from the consistent flow you were using before
i think a trapezoid shape would work out much better
00:23:592 (4) - having the strongest note be on the sliderend just kills any intensity from it, just bad rhythm choice
From ranking criteria: "Background images must not exceed a width of 1920 pixels and a height of 1200 pixels."
BG is 2182x1200
00:18:876 (3) - random break in the rhythm you were following, would continue what you were doing before
this actually would work better as just a circle, the slider maps to nothing if you leave it the way it is
