I agree that this could be a very beautiful model if she had a decent
hairdo and the photographer had properly used the lighting, exposure
and posing of the subject. It is a shame that the hair was blown
out.
Here is my effort at retouching what was there. All work done in
PaintShoipProPhoto X2, using curves and levels adjustment layers,
denoising, highpass sharpening, PWL and addition of makeup via
painting on a separate color layer and adjusting opacity to taste and
using gaussian blur to blend. I also reduced the height of the top
of the hair, straightened and cropped and added a little bit of
vignette.
