So this guy is supposed to be a scrap merchant sort of dude. The color choice is a bit cliche (and maybe a bit over-saturated), but he's theoretically going to exist on darker, more muted backgrounds and I want him to pop out.

I'm not sure about outlines. Black? Colored? None? I've got outlines in some bits and none in other bits right now as I was experimenting. I tend to start making one-pixel changes and getting carried away with details and adding too many colors if I get blocked, and that's what I started doing here, so I decided it was a good time to post and get some broader crits I could focus on.

What's wrong with it? It should be noted that at fullscreen, the theoretical game I'm looking to make would be 3x resolution on a 1080p monitor.
