I saw this person model one of the best faces ever well more than one so i tried to do it too. As you can see
I have failed but since this is the first time i have modeled a head in mudbox I think it might go a little faster and better next time .(I need to fix the eyes i really liked the nose though the mouth needs work and damn flabbin ear it was fun building it )I started out using a plane primitive
it took way too long about a half a day . next time back to box modeling.
