This creature feeds off humans. As it feeds it grows human skin. This is a protection system it has imprinted into its DNA which helps it be a super predator.

Character done in ZBrush, Maya, and smoke done in Photoshop.
This was a little task I set myself. I wanted to create a character mainly using Zbrush and only then the rendering done in Maya - i did achieve this and I am quite happy with the outcome.
