This is my first, and so far only, original headsculpt. Mr. White of Reservoir Dogs has been made from a Gotham City Thug movie master, ceramic porcelain and greenstuff. The head was made as follows:
I made a ball of Ceramic porcelain, shaped out a chin and pushed up slightly at the bottom to make it a basic skull like shape. Then I let it dry. Once dried, I sculpted the features on with greenstuff mixed with ceramic porcelain (a method I learned to conserve my greenstuff, which otherwise goes fast). Then I painted and let dry. Once that was done, I dremeled out the underneath of his head, as you would for making a peg jointed head into a ball jointed head, and dremeled the ball joint. The tricky thing to remember is to then put greenstuff inside the outer rim of the ball joint, otherwise the ceramic porcelain will be to hard to put anything inside.
As you can see, there's also a soon to be posted Mr. Pink and Mr. Blonde. Mr. White only comes with his gun, but they have plenty of accessories.
