Yeah the feet look kinda off, the biggest problem though is the yellow shades. So I've done an edit to give you a quick idea. (if it's slanted slightly, it's due to drinking excessive amounts of alcohol, I'm sorry if it's really bad

). I've boosted the colours slightly but you can easily fix that when it's done.

I've no idea what the boots are meant to look like, it looks kinda messy down there. The magic shit I imagine should be glowing so you creating a glow on his body and want from it would improve the sprite.
Anyway that's enough from me.
