Artist Bryan Silva says:
This is a Witch prosthetic for my 11 year old daughter. It was sculpted in Monster Clay and cast with Gelatin that I made based on a recipe from Matthew Mungle. This is a make up test application that I did. She’s only in the prosthetic in this video, not her costume. We went to the Halloween store afterward and then to Target and she had all kinds of people looking uncomfortable. :)
