Today's CG Artist, Tyrone Maddams, is another guy I stumbled across when I was looking for 40k wallpaper. According to his bio he's worked on a number of CG Cinemas for games including:
Transformers: Revenge Of The Fallen, Warhammer 40k: Space Marine, Warhammer 40k: Dawn Of War 2, Ghostbusters, Bioshock, S.T.A.L.K.E.R: Shadow Of Chernobyl, Edge Of Twilight, Mafia 2, Borderlands, The Darkness, Tomb Raider: Legend, Tomb Raider: Anniversary, Hitman: Blood Money, Hitman: Contracts, Constantine, NBA 2K9, Ultimate Band, Justice League, Duke Nukem .
He works for a company in Australia called Plastic Wax. These guys were responsible for the amazing opening Cinematic in Dawn of War 2 (that's where the above space marine comes from).
Here's a couple more stills of his work. It's intersting that most of the 40k Guys also have Bioshock stuff. Guess when you get good at "Bulky guy in a suit" it just goes hand in hand.
