The SRP

Although the two strips Staci Roberts Petrezza has appeared in are set maybe 15 years apart, the only real physical difference in her design so far is her hair. For the younger version I stuck her face behind sunglasses. When I dug the scene file out again two years later, I just changed her hair to what I'd already planned as her "older" hairstyle.

I probably could have added some lines to her face, though.
