Because you can't really draw all that well.
Some days are just the best. Usually for me, a good day is sitting down and drawing. Anything. Usually something odd. Sometimes other people ask me to do drawings for them and I say yes. Because I like to eat. But more importantly, because I like to draw.
This is just a tasteful selection of some children's book illustrations, show flyers, album covers, caricatures, T-shirt, web graphics, and paintings I've done over the years for people just like you.
