Realistic fursuits

Hey again! Coming back with another question. I'd like to begin making a realistic fursuit head. So I'd like some form of tutorial, I've looked all over the place but could not find somethign that could help. Since it's halloween I've found a lot of materials, foam and liquid latex, other things so I'd like to use this to my advantage

Could anyone teach me ( step by step ) how to mold or do something with the head? I assume you mold it then do somehting with latex?
