Alright, here is the final colored pinup.
However, since the souvenir book is printed in black and white, I converted the pinup to grayscale. After playing around with the contrast, here's how it turned out.
I sent it over to the good people in charge of the San Diego souvenir book before the April 15th deadline and I got an email confirming that they received it. I guess I'll find out if it made it into the souvenir book once I get to San Diego in July. If it made the cut, it'll be a cool surprise. But if it doesn't, that's OK. It was fun to work on.
