Here are some shots of a rough sculpt I did for a Classics Hound. Using a Movie Landmine and some Plasticine Clay I tested this out. I need to do some shaving of the legs and remove the black rollbar on the back of the cab to get his arms to fit and to transform, but it will work. The final piece will be made out of Apoxy Putty. Any suggestions before I go for the permanent putty?
