First mod, let's see how it goes.
General
Mapset won't be ranked without an 1* difficulty of some kind, so you'll definitely want to make one.
Maybe make a 6* Extra and/or 8*?
Try to make Kiai time consistent across all difficulties.
Add epilepsy warning b/c storyboard.
Normal
00:24:991 (1,2,3,1,2,3) - Patterns like this might be too difficult for newer players to read.
00:42:616 (1,2,3) - Might want to nerf these jumps as well, they feel out of place in a Normal diff.
01:02:116 (2,3,4) - Same as #1
01:31:366 (1,2) - Try not to have sliders overlap like this, it can be hard for newer players to read.
02:47:366 (1,2,3,4,1,2,3,4) - Similar to #2, they feel out if place in a Normal diff.
Hard
AR seems a little too high here(might just be me though...)
01:55:616 (2,3,4) - Maybe nerf these jumps? I feel like I could go either way with these.
Hyper
00:40:490 (2,3) - Ends are not snapped.
01:09:366 (1,2) - Maybe extend the reverse slider out and remove the circle? Although either way seems fine.
Extra
01:47:366 (1) - Maybe change this slider? Looks a little weird IMO.
Excors
02:35:366 (1) - This slider is very slightly offscreen
That was all I found. Love the mapset, keep it up!
