Hi Ben,

it's just a base mesh made in Maya, with some sculpting and detailing work in Zbrush.
Nothing too fancy really, and the teeth were from the previous model I did, just reshaped to fit his mouth for time savings sake.
His little beard is just made up of a cylinder deformed with a lattice and then duplicated/repositioned multiple times etc.

I have since decided when I have some more spare time to polypaint him. Just have to see when I can get another day off work! lol
