wow!! this is such a cool piece!the image fits perfectly in the space and your use of dark tones leads the eye to the eye in her mouth(no pun intended)which is a wonderful creepy touch.It creates a whole line of speculation into the scenario of the image.
Haha! My mate did a manip of that photo here [link] It's uncany the number of perceptions one can get from such a great stock image. Anyway, I love your version. Very nicely done. It deserves all the pageviews it gets! Great Job!
