This one was originally just a 3D model of the hell hound's head that I made quickly in Zbrush a couple years ago
that original Zbrush sculpt can be seen here:

Anyway, I decided to use it as a base for a speed paint.
Spent about 5 hours so far, and was trying to make it a little ambiguous. Are the dogs attacking, or wondering what is wrong with their friend???
