Okay so I bought a few sculpture books to learn that, and realized I can just take some photos of faces and load them into a face room like poser has then turn it into a 3d format and use a 3d printer to print molds for the skin. Then it is just a matter of drilling holes in the right places for the cables that attach to the servos for facial expressions like Hanson does. Not quite as easy as it sounds but I think it will work.
