Veraj Moving Jaw Mask

Veraj Moving Jaw Mask:
I have a video showing the movement/functionality of my mask here:

Moving Jaw Mask I had an idea for when I wanted to have something to wear at conventions.  I made it with a 3D pen and painted with acrylic paints.  I have since sold a bunch of masks since starting making these in Oct 2019 (with no real prior sculpting experience before).
