I started in 2002 at Magic Mountain working with Fasen Arts. Fasen is known for bringing the graphite and airbrush style to retail caricatures. Airbrush is a great way of getting highly rendered caricatures in a speedy and versatile way. There are many different ways to use an airbrush so you can get a variety in styles. Recently I did a 3 different caricatures in 3 styles.
Dog- A more cartoony style ala Tom Richmond, but of course, not as skilled.
Jean Paul Belmondo - This one is a more rendered style. A little less graphite, a little more paint.
Joe Rogan - This one is definately more portraity. Almost not an caricature, but a crappy portrait haha, but still a variety of style possible with an airbrush.
