"headbanger" fighting... boat monsters?

here's a character i originally sketched 3 or 4 years ago for the dominance war 3 contest and i just recently tried to paint a better version.  he's some kind of warrior with a stone giant's head for a weapon.  when he's holding the head he's as strong as the giant, as heavy, and has stone-like skin.  i might finish up the 3d model of this guy if i have the time.
