Don't know how I missed this; I've literally been looking for something like this for the past few years.
Closest I found was 2D Character Creator by exportVar, and I prefer yours over theirs.
Do you do commissions? The only thing that would make this perfect is headgear. Hoods/Helmets/etc.
I'm no stranger to drawing but I'm terrible at pixel art, and recreating your style is difficult for me.
