Chris J. Anderson is a concept artist and illustrator working in both the film and video game industries.
He was working with NCsoft, but beyond that I have no information as neither his web site or his blog have any biographical or client history information. (There a link on the web site for a future client list, but it’s not active yet.)
His site is divided between environments, which is evidently his area of specialty, and props & vehicles, characters, illustrations and other sketches and studies.
There is also no information about process; though it looks to me like much of it is digital painting, with perhaps some watercolor or gouache pieces and traditional drawing materials in the sketches.
