The main issue is that the guy is really, really bulky. I think I drew a stick figure comic that vaguely eludes to his proportions.

That is his general, non-artistic appearance however. Still humanoid, but rather haunch and frankly quite bestial. He's also no looker, though he has less prominent tusks. That is to say, he could close his mouth and hide them.
