The slaughterer

This selfie was made using three flashs : one with a green gel, one using a blue gel and another one with no gel on it. I was standing in front of a black backdrop that i splattered with baby powder to add texture to it. I used fake blood on the knife. It was shot with a 90mm macro lens to have a lot of texture on the skin. This selfie was made for a Halloween series of portraits. What do you think about it?
