[General]The storyboard is a bit distracting, specifically the rings on the edges (before the first kiai).
I think if you made them slightly more transparent it would be a good tradeoff. You could probably do it to the spinning squares too.
Maybe display the seizure warning? I think the countdown is unnecessary too.
[CDFRAVE!]Not quite sure why this was on grid level 1. It looks like you've shift-snapped most of the notes anyway.
00:55:905 (2) - Up one with grid level 3.
[BUBBLEGUM RAVE!]02:08:248 (6,7) - I don't like this big space here. I think you should shuffle (7,1) around a bit to make it even.
[LILYPOP RAVE!]00:04:819 (4,1) - This gap doesn't look like a jump, so I think it might look better if you moved the stack closer to the 4.
00:04:991 (1,2,3) - This stack would look better if you moved it closer to the previous combo.
00:55:562 (1) - This would sound cool if you left the first hitsound at 66%, but immediately mute and fade in to 66% over the length of the slider.
02:39:105 (1) - Make sure this is properly mirrored with the (2). At the moment it's a little too far left.
02:41:848 (1) - This looks really out of place up here. I think it might look better in the top right corner instead, or maybe even stack it with the end of the slider.
[CANDY RAVE!]Crazy jumps ahoy! Nice.
Starred.
Probably too nazi for kudosu, but eh.
