Iron Fist at a recent convention. They specifically asked for "Disco Collar" version. If I had a rockin' dragon tattoo on my chest, Im pretty sure I'd wear this kind of sure ALL the time too.
I agree I rather wait until Im in the hotel to do the larger nicer sketches, but this was just a one day show, so you kind of have to make due. I don't think I'm capable of the quick sketch, I envy those guys that can do a rough sketch that looks effortless and genius. Then bang out like 10 a day or more.
