Arnulf Hauer - PnP Character

This is my son's pen and paper character for "Hero Kids" (he's just 4 y/o) he loves dwarfs, hammers and smashing foes. Did this in a dark tone to make it a part of a bigger piece, but that piece never happend to be created (second part is coming next but third part doen't exist). The green shine will come from the secon character so stay tuned
