That Dwarf's skin has too much subusurface scattering. But they may have overdone the effect in order to show it off.
Subsurface scattering is a technique which simulates how light passes through skin and wax. Ie, if you put a flashlight up against a block of wax, the block would glow, because the wax scatters the light in all directions inside it. The same happens with your skin, though to a much lesser effect. It happens most around your nose and ears. But hold your thumb up to the monitor, and you should be able to see the skin around the nail glowing, if you're in a dark room.
It's the next big thing in realistic character rendering. Requires shaders though. I've seen a lot of people misusing it in 3D renderings, I think it might take people a while to learn to avoid that wax look.
