How It's Done

So, the folks in New Zealand say they'd like me to do a demo about how I paint. I tell'em, "How about if I do a paying job while you watch?"
The first day of the convention I do a pencil sketch, then the following day everyone gathers around and I hook up my travelling scanner, Wacom tablet and other goodies to my art laptop and projector. I explain what's happening and sprinkle in lewd jokes, anecdotes and art lessons.
Everyone had a great time!
