Last year, I talked to Eric for about half an hour as he did one of my favorite sketches from the con.
This year, he was at the ever-busy Illuminati booth and he was also set-up w/ his Black Velvet Studios crew, but I couldn't find them for the life of me.
Eric's done some work in animation w/ Peter Chung and entered comics through Verotik. They even published a sketchbook/comic about him, before he moved onto some Wildstorm titles like: Mr. Majestic, Cybernary 2.0 and the Ladytron one-shot.
Right now, he's back in the world of animation, but hopefully he'll be doing some more comics in the future.
He also puts together these amazing sketchbooks, which sell-out fast, so get there early. If you can find him, that is.
