Who is Sally Volt?

Something below looks a little threatening. Here's a quick sketch from my sketchbook. A little warm-up for the work I have ahead of me today. I am doing samples for a publishing company and will be trying to get their house style down. So far they like my first pass, but as expected there is some tweaking to be done. And because of the Confidentiality Agreement, I can't share anything. So you are stuck with my character (developed with writer J.C. Vaughn) hanging on by a vine instead. : )
