learn the difference between 3d and 2d before posting. theres a difference between depth perseption and 3d art work. i shade = depth perception, he used a 3d art program, and therefor his is 3d. if you cant look at something and tell the difference from it being 2d or 3d you got some problems that no one here can help you with.
i hate it how people that dont gfx think they can tell you whats what when your a gfx'r -.-
