i like the material without the specular better, looks great.
cool char man 
morph targets are gonna have to be implemented in the games, since everyone makes expression sculpts, (making a sculpt without an expression seems so boring to me too, i love asymetry on and posing it all over the place)
but when it gets to the game hes not allowed to go pull it constantly or it wouldnt look right.
id hire you for my game anytime.
I think more attention should be focused on the feet, they seem forgotten about.
