I don't like the hands, but Two-Face himself is quite good.
Nice sprite, I'm just missing an evil grin on his face. He looks a bit unemotional.
Quite a nice little piece you've got here, but you've tried to cram too much detail into his face which has resulted it looking entirely blue except for his cheeks and eyes which look flesh coloured (on both sides). Sometimes it's best to sacrifice detail for readability when working on a small scale. The neck/collar region is also looking quite bulky and unatural.
Nicely rendered, but isn't the point of a sprite to not include elements from a scene? I don't think the edges of the canvas you drew on should be clearly visible.
The coin effect looks sweet! Overall great job but your AA and pixel clusters need work.
I really like the pose, athmosphere and colors of this. Nice work. His neck seems to stick out in a weird way though.
