Here is the original portrait of Cindy I made last autumn. This image is actually the first image of the comic "For Sale!". It was the time when the forum was down once again, during which I made series of portraits to pass the time. (You have already seen the Gwen and Carol portraits before).
I played with this image and made the sales flyer later featured in the comic. That particular flyer inspired the comic and it was done in a few weeks.
(The portrait itself was inspired by the eyes of a random girl I saw while surfing the net back then. Can't find the darn picture now.)
