I found the old concept art for my gas mask I made at Keene State. Made me realize I never posted it, so here it is. Starting with a plaster cast of my face I built up my mask with plasticine. Covered it with Vaseline and then covered the whole thing with celluclay. Once I it was dry I used spackle to smooth it all out. Some paint and other attachments for the filters and pipes and there it is.
