I have been doing more cartoon illustrations lately. This is how it works - I start by submitting a rough sketch for the client based on what they need.
This client, Rambling Russ, wrote "...me jumping off the picnic table, head down, feet flailing in air, great big grin on my face, and in the foreground maybe 3 or 4 seated including the cute little red head I was trying to impress. Although I was much younger, we can keep any illustrations of me in my present bald headed form, mustache, but no glasses. A close resemblance to me is not important to the illustration."
It's all handled through email and Paypal.
