This project was an exciting challenge. Everything apart from his t-shirt was sculpted by hand (pore by pore) and painted with polypaint in ZBrush. I made his shirt in Marvelous Designer, retopologized it in Maya, and textured it in Mari. Hair is XGen and he was rendered in Maya. Composited in Photoshop.
Thanks for looking! More process images on Artstation and Instagram.
