Portrait of Prowl head that I will be designing my helmet after. The red forehead wing will be added later after cast is made with standard vinyl or acrylic plastic cut to fit.
This mannequin head I found in SD at an old downtown apartment rooftop. This will be used to sculpt a helmet from layers of modeling clay.
After that I will make a mold of the helmet and then create a cast helmet from the mold. I had to construct a sturdy base that allowed the head to sit level from its original crooked position.
The white helmet will be a guide for the curvature of final model helmet. Found the white helmet on craigslist.
