Mine's basically a merge of multiple skins, with edits of my own.
I used the Nexus Slate skin as a base, and then removed some of the parts and added some from other skins.
I removed the skin's cursor and am using Osu's default one. For some reason, I like the default one the most.
Replaced the hitcircle image with a hitcircleoverlay from a different skin. Used a different hitcircleoverlay for the overlay as well.
Basically just merged two overlays to create a hitcircle.
This makes the hitcircle seem like it's made of glass. Although a bit dumb, it actually looks pretty cool.
It kinda reduces accuracy though.
Also merged the skin's spinner with Neosu's spinner. It looks better.
I replaced the big ranking icons with pictures of chibi anime characters, which I got from different beatmaps. Had to resize some.
Lately I've been editing original pictures myself and using them as ranking icons.
I'm often making edits here and there, so the skin's never really the same.
