He does it semi professionally in that he does commissioned pieces--he really doesn't like portraits--it's probably his weak area--but he does them for me. Last year he did one of my 3 year old daughter that is absolutely stunning. He actually went to school for Industrial design and concentrated on toy making but the market for that isn't so hot in GA and we don't want to move away from our families . His parents own a printing company and he does all of their layout and graphic work. His intentions were to go to art school after GaTech but never did--I keep encouraging him. He love sequential art, and if you know what that is (comics), you know that we'll never get rich that way!
I can't remember who asked but yes, he did do this one w/ a tablet. He does a little of everything--he has a large Intuous and all of the pens/airbrush stuff but he does traditional painting and pencil and paper drawings too. A lot of times he will pencil things out (if it's a sketch or pencil drawing) and then scan it in and color it digitally. It just depends on the subject.
Thanks for all of the kind words--I like to show him that other people appreciate his work too--and that's why I share it around even when he doesn't. Happy New Year!
