Damn, I actually forgot to mod this. Take these 2 Kds for the delay.
[General]
Have an optional suggestion: What about limiting the combo colours on 3, only using the characters' hair colour? So that would be 1 pinkish, one blonde and one blue. Values for those colours would be 255,255,119 for blonde, 214,10,61 for pink and 0,64,128 for blue.
[Easy]
|I can only hear a different drum at 00:46:578 (4) - , meaning that they wouldn't fit at 00:45:308 (2,3) - . This probably effects other diffs as well.
|01:22:451 (1,2) - Tiny cosmetical issue, I think 2 is too close to the edge of 1's sliderborder. You can give 1 a rounder shape to form a blanket, that will already solve the problem.
[Normal]
|00:24:514 (2,4) - I think the guitar strings are dominant here, suggesting to extend those sliders.
[Hard]
|00:16:260 - Having nothing on this beat is kind of awkward. The previous slider tries to follow the vocals I guess, but that wasn't well-realized. If ypu wanted to pronounce the guitar, then 00:15:784 - lacks of emphasis. I suggest having a circle at 00:15:625 - and having a slider follow that circle. The new slider would end where the original one ends, but like this the silence on the red tick seems more reasonable.
|01:19:277 (4,1) - 1 could be a bit more curvatious to avoid this overlap.
What I saw here is that you used a lot of polygon patterns, probably to provide some structure. Unfortunately, that was done on flow's costs. It's not much of a problem, since the diff also works out with the current flow, but it could be more clean (
Example). By altering slider shapes or directions, this can be improved a bit.
[Insane]
|00:21:498 - What does this slider follow? Can't hear anything special here.. Also found in Magi.
|00:06:895 (4) - Flow suggests a horizontal slider, just like 00:05:625 (5) - . This current one isn't as good I fear.

Nice.
Wow, this was tiny. Since I didn't really have anything to say, have another star. I hope I still was helpful and I wish the best of luck.
