I recently attended Gen Con where I had an artist's table. The convention was great with lots of cool things to see. It was fun seeing all the artists whose work I enjoy. I generally don't do a ton of sketches when at cons, but this one I did quite a few.
Sorry for the quality of the photos, I shot them with my cellphone so they aren't very hi-rez.
One of the coolest thing that happened to me at the show was the esteemed Wayne Reynolds traded an original painting for one of my originals.
