This is a game character. The soldier sculpted in ZBrush and final images rendered in Marmoset Toolbag 3. I used the new skin shader with PBR shaders and textures to really bring this man to life. For this character I used the face of Vincent Cassel the French actor as reference. I made a tutorial about making the polygon hair: http://kollarandor.com/tutorial/fast-way-create-polygon-hair-character-maya/
The head has detailed geometry with great edge flow that appropriate for facial rigging and animation.
