I haven't seen the base image, but the same image was used in a (very) old manip on Comics2Film. The notes there say that the model is Angelica Bridges.
Comics2FilmIt's fun to look at the two images side-by-side to see the differences.
Even if this manip doesn't change the base image that much and the image has been used before, I still think it's a good manip. Part of the fun of manips is finding the perfect image and making the changes necessary (large or small) to give it a comics theme.
(While also giving credit where credit is due, of course...)
Just my 2 cents...
