They are required to create art that that reflects the style, theme(s) and genre(s) of the game based on the brief from the producer so the 3D artists have a concept which can be used for their art. The qualifications that may be useful for becoming a good concept artist are: degree in graphic design or fine arts. A portfolio would be a good demonstration of your artist and storytelling ability along with a minimum of experience as a graphic designer or a concept artist.
