Space Hulk Deathwing - Interrogator Chaplain Heads

Interrogator Chaplain heads for the game Space Hulk Deathwing.
I had to create several heads for the Chaplain class customization.
The first one was finally used for the Apothecary class.
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.
