The mouth interior for the Grommash Hellscream fan art I'm working on. I did my best to get close-fitting functional bite, despite the natural underbite. In humans, if there is even 3mm of spacing between the upper and lower teeth, you start speaking with a lisp and have trouble eating. I wouldn't want Grom to be drooling all over himself, so to have a semblance of normal function, I opted to make the entire upper row of teeth the smaller row. The teeth interlock normally otherwise, just in reverse, basically.
