Wolf-man (composite)

Hello, glad to post 3D work here.
It’s showing a man revolving to a wolf after hit by kind of special Light Source.
It my good practice how to composite a 3D wolf head into a real photo background with human body.
It’s not a commercial use art piece.

I’m the 3D artist who in charge the wolf head modeling, texturing, fur, rendering and compositing.
Concept idea behind this art piece and final matte painting was done by MirageWorks.

Here is the link of the original photo before composite the wolf's head.
