Guild Wars isn't really known for having a science fiction element to it, but this concept art shows off an extremely steampunked Crab Fort, lumbering across the horizon. Enormous cogs and gears are evident in the construction work that looks like something straight out of a psychotic version of Burning Man. Everyone is standing around fairly calmly, not paying much attention to the GIANT FREAKING WALKING CRAB VILLAGE!
Daniel Dociu of ArenaNet has worked on many pieces of award winning art, including the Crab Fort above, and the Fish Fort, which looks like it could be a great model for a drive through fish restaurant. He won two Master Awards from EXPOSÉ 4, one for Environment Design (the crab fort), and one for his Urban Canal which won in the Cityscape category. You'll get 'em both if you pick up the book from the showcase.
He was raised in Transylvania, worked as a toy designer for years, and now focuses on creating concept artwork for Guild Wars. If we can find proof that he's actually a vampire, he might officially the coolest concept artist haunting the halls of gaming companies to this day.
