It's important here to distinguish between someone who's very good at drawing, and someone who's a multimedia artist. Being great with a pen and pencil is no use if you can't realize your graphics on a computer. Having great computer skills is no use if you don't have the talent or imagination to come up with an innovative design in the first place. A multimedia artist will be as computer literate as they are creative.
This role belongs to the entertainment industry, and the best people at it work on the incredible special effects we see in blockbuster movies. You'll need a degree in graphic design, and a great portfolio to show off to prospective clients. Chances are you'll be working for low pay at the start of your career, but climb the ladder, and the big bucks will roll in.
