Concept artist Graven Tung has, in over a decade working in the field, provided pieces for clients such as Blizzard, where he worked on both StarCraft II -- right down to Gabriel Tosh concert posters -- and World of Warcraft's three major expansions.
He also did some work on SOCOM II, as well as driving game Stuntman II (which has a little Batman flavour thrown in).
You can find more of Graven's work on his personal site (thanks Concept Art World!)
