I've been playing around with this little precious, and while I haven't come up with a good color correction, I was working more at trying to discern some of the detail. I went to CMYK and fiddled around with my favorite calculations, and came up with an image that indicates pretty clearly to me that the lightness at the bottom of her face is part of the light streak of damage that crosses the photo on a diagonal - lower at the right and just below her ear on the left - rather like airbrushing.
It looks as if her little dress covers most of her right leg and causes it to blouse out on the side (check the line that crosses in above her feet that looks as if it might be a hem), and I think you're right about the bow on her shoe and that most of what we're seeing is the sole.
As for the pattern, I'd clean up all the white and then look for possible repeats that might give you an idea of where to place bits of color and shape that would coincide. I doubt that there's much else you can do with that.
Very interesting and tough project!
And you have the Dutch grapes to blame the muck on our Aussie distribution crew? For shame! We know your act. Tess, you don't have to take that. I'll back you up! Ms. Hun, the angel with the harp fools no one!
(I wuv U!)
P.S. I hesitate to post my image, because the color is awful. As I said, I was more trying to pull out detail. The color correction is a toughie as well.
