Yeah I don't like the legs :(. But it was just something I made when I was bored, so I don't think I'll change it^^.
Thank you anyway !
it looks a bit strange, I think his body is biger than his head 
Your proportions need some work. The legs and arms are bent funny, and the head is too small for the rest of the body.
This piece and the previous one look like outlines are a hindrance rather than a help to you. Time to free yourself from them!
Nice colors. This would need a background to isolate it from the default PJ grey.
There's some banding here and there, of the 'align pixels across large zones' kind. The pixel clusters deserve more attention, also stressing the 'natural' pixel angles would make it cleaner/sharper.
