Working in warm and cool grey markers (prismacolors, if you're a stationary nerd like me), Chris Stevens' greyscale commission work is incredibly unique. That's an easy word to throw around, but where the Skullkickers artists work is concerned, it fits. He mixes soft smooth lines with amazing textures (seriously, just look at the Dark Knight's glove), and pulls it all together with perfect use of light and shadow. Who needs colour when you can do this with greys? Check out a ton of his work below.
