Something I can finally share. I had the extreme honor to work for Digital Dimension and Meduzarts as a Creature/Character ZBrush artist and Texture Artist (on Cyberdemon) on these Doom images shown in EDGE Magazine. Credit goes to ID Software for their awesome franchise and characters.
The original character model and textures were done by Id Software's Lead Character Artist: Jason Martin (https://www.artstation.com/artist/believerdeceiver and http://www.believerdeceiver.com). I had the pleasure of upresing the marine to withstand a 12-15k render and creating wear and tear on the suit.
For the Cyberdemon I had to re do all the details on the head and I created the wear and tear on the whole creature. The textures had to be redone as well.
