so Before FE. I finished up my first Trial and Error head base, of use your own eye style heads. I choose a Cat/cheetah (did a super quick air brush) because it basically is one of the few critters that have smaller muzzles that are super close to your face. So I wanted that amount of space to work with. and then translate it to all my others heads, such as canines, dragons, bears, horses, etc.
Figuring this out, helped me work out a complete redo of the rest of my future heads, with how the jaw works.
when u have a head/mask that close to your face. You cannot get away with the "crocodile" like jaws, were the hing is far back around your ears. So I had to work out a proper overlapping jaw that allowed the jaw to open and shut, and look like a proper mask. The springs are hidden in the cheeks and under a flap for easy access.
the next hea dupload will explain this better.
