One of 4 heads with portrait likeness of 4a-Games employees I made as Freelancer in 2007. No scan data were used. The similarity was achieved by visual comparison of photos and 3D model in the software viewport.
Screenshots were done in Maya viewport in 2007. ~10 years later I have possibilities to achieve the next level of the Metro characters looks, not in Maya viewport only, but in the game engine.
Added old works to Artstation page for fun
