Re: Game Artist
It would be a good idea to aim for a position that's both in wide demand and play to your own strength. There are many different kinds of game artists: animators, technical artists, character artists, environment artists, concept artists to list a few. Each of these specialties have distinctly different portfolio requirements. From what you've said it sounds like technical artist might be a position you want to look into. Search online for portfolios of other tech artists or job descriptions on company websites, and cater your portfolio accordingly.
