Actually, the big accomplishment here was managing to get the colour decent. The reference image was a monochrome picture of actress Jennifer Morrison, from an advert for her new TV show. There was no use of the source picture in the production of the final image, of which I'm terribly proud. (Although that did at first result in a slightly "tranny"-looking face: see below, where I had to lasso, copy, paste and squash her back into shape).
Finally, I slapped a mask on her for fun. Cause I dig the superheroes and because Marvel Studios should make a good chick flick version of one.
