I don't have a graphic novel or anything specific ... I do occasional panel cartoons here and there, mostly for personal enjoyment. I might drop off a quick doodle at the doctor's office, spur of the moment thing. I am working on collecting everything I've done since the early days ... primary school in the 1970s until now. There's a lot, between newspapers in Australia and the US, college papers in California, awards, etc., personal comic strips and other bits. My "training" is in technical illustration and print-related graphic design. If you're curious, let me know.
This is one that goes into a Kia newsletter which is distributed in-house to technicians across the US. I'm a contractor for Kia in a graphics capacity; I draw all the illustrations in their little manuals that come with each new car, plus the layouts for the books. Sample here as well.
