And this is Cerberus if you don't know what he is or who he is here's a good description about him. "hound of Hades", he is the monstrous multi-headed dog that guards the gates of hell to prevent the dead from leaving. Basically it works like this none of the living can't get past him and none of the Dead can't leave.

This is basically just a simple sketch.

Cerberus my new pet or you could say. guard dog.
