Space Hulk Deathwing - Apothecary Heads

Apothecary heads for the game Space Hulk Deathwing.
I had to create several heads for the Apothecary class customization.
I've done the model, high and low poly, in ZBrush and 3DSMax and the textures in Substance painter.
Renders in Unreal Engine 4, "clay" renders in Zbrush.
