kenevin I'm working full-time as a game artist/designer. I worked as project/art lead on Mush, and most recently created the game Mortar Melon. I also did art/design for the game Q.U.B.E..
I'm also working as lead design on an upcoming first-person survival horror and lead artist on a 3D strategy game. These are all indie titles, and pretty dependent on technical know-how.
I have a friend that graduated from my course who was heavily concept-art focussed. He now works at Codemasters as a concept artist after doing a long stint as a QA tester. It's fiercely competitive, but if you love concept art then that's the way to go.
