Twitch just threw up a great link to Miles Teves’ personal website, which features some amazing concept art from films he’s worked on. There’s really good stuff on there, and some of it recognizeable from the end product, like the work for Slither or Chronicles of Riddick.
And speaking of artists, check out the concept art of Craig Mullins, who does a lot of video game work. Or the macabre paintings of Luke Chueh. And of course, any chance I get to plug Brandon Bird, I will. The Anguish is the only thing hanging in my living room.
