They seem best suited for humour because of the way they look. Their over idealized physicality, and their histories. Supergirl also strikes me the same way. I'm curious, since I'll probably never ever experience it for myself, how do you do sketches at con's and then post some of them here? Is it that you carry a scanner with you, or do you keep the works and post the finished art on to the purchaser/client later?
I live in South Africa, so finding your stuff is rare enough, and I'll never afford to get to a con in the US or elsewhere, but at least I can see your beautiful work here.
