Unfortunately, not right now. I seem to have a limited amount of creativity and time to do art, and since I'm living off my art, I need to make sure every moment is spent in either personal fun or actual business.
So, if you can find some way of figuring out how to inspire my muse beyond my ability to control it, you might get something for free.
Also, if you find me at a convention, I sometimes do a "Ketch -a- Sketch" free sketches. Everybody gets ONE!
