At the beginning of the year a friend of mine, Miguel A. Cardona Jr. posted some characterized profile pictures on facebook. They turned out to be a project of his, check them out. He has a tutorial on the process, too.
a Brief Caricature History on me: In a past life (college) I would draw caricatures at campus events. I really loved doing it, capturing a likeness is a joy. To keep them speedy 10-15 min. I used sharpies and crayons. After a night of breathing in the sharpie scent and laughing with people I would usually end up hoarse, but with a smile. This was so much a part of school life I made one for each person in CSH (Computer Science House-a group I was in during college), which were used for their yearbook. It was great to go back and make another one tonight.
I am always up for a trade.
