I've been working as a freelance commercial artist and designer for over 30 years; I don't remember a time that I didn't draw. My body of work is fairly eclectic in its nature, and isn't specifically geared toward one type of illustration, however, all of my illustrations are realistically-styled. My preferred media are graphite and digitally-colored graphite.
