So I made this base out of scratch board (like the material tissue and cereal boxes are made of but way thicker).
It has an adjustable moving jaw that is highly reactive since it has little elastics in the edges.

I have just finished meche-ing and it is awaiting a second coat of paint.
I used a different method of meche where you yous watered down glue instead of flour and water. Makes it dry faster and more durable. It looks great so far! Just have to cut out the eyes. :)
