Its been a couple of years since I made a mask so I got out the clay and started on a dragon. Dragons are good because they are not real so there is a lot of leeway if I make anatomical mistakes. Heres the start, the finish will not be perfect but it will be a result.

Far left, basic cardboard structure, left, clay with taxidermy eyes. Next step is to cover the clay in vaseline and papier mache all over. The foam horns will come out of the basic structure and be attatched to the papier mache one.
