Luis de la Fuente, the sculptor of monster skulls.
Ever wonder what those cinematic beasts look like on the inside with their leathery hide, layers of bulging muscle and alien blood stripped away? Nothing left but the smiling, gleaming skull. Luis is like the Predator hunter (yeah, he sculpted one of those, too): he collects the skulls of monsters from all over the universe and realizes them in clay to reveal them in all their ossified glory.
Here's my painted version of Luis' most recent skullpture, the Locust Grenadier, from the Gears of War game.
