Having painted both old and new ones of these, I still find these oldies to be the best. Tons of character and goofiness in some of the old sculpts. It's a treat to see one done up so well. Nice!
I have to admit that I like the mean teeth of the plastic goblins GW makes, but I still keep coming back to these minis. They are awesome. I like your colors. I think if the opening of his mouth were black it would give more contrast to him.
