Nice! Thanks for the tips JimmyTime! I will start playing around with different ways of slicing (was thinking a forehead to back-of-jaw diagonal cut would maybe cut down on supports.). Definitely will try more shells, higher layers. S3D I most likely will have to invest in, but later (so broke!)
Let me know what you think about the vertical column I put in the back and the strap strategy in general. I made it thinking an elastic strap would anchor with a loop there and attach to mask by Velcro (also made a recess area on mask cheek for the Velcro). I thought this the best way to go so put on/take off would be easy but I'm 2nd guessing now. Something like snowboard bindings would sure look better but difficult to remove, I think. I might make a hard frame for the elastic to thread through (mainly for looks).
