It's really unfortunate that a lot of photographers don't bother to fill in the "Photographer's Comments" section when they submit a photo to a challenge... especially when they check the box to request an in-depth critique. I have stopped offering in-depth critique on photos when the photographer chooses not to include his/her own thoughts on the image when they submit it... You might want to consider this in the future.
The skin color looks unnatural, as if there were too many adjustments made (shadow/highlights maybe). Also, I wish there was a more appropriate backdrop.
Nice picture... I think you could have benefited from doing this in B&W; the texture would have shown through so nice... perhaps cropping down to her face would have helped too. You almost got a 10 from me.
