I used Photoshop CS
I only did a few things to this image. The very first thing I always try to do, to see if it works is auto contrast, which worked here.
Second, I duplicated the layer. I then went to image-adjustments-shadow/highlight. I currently have it set on the default settings, which seems to work 90 percent of the time. The highlights are then brought out on the entire image. I left her alone but, erased back in the background, so that it was darker, like the original image.
I then did auto contrast one more time.
Then I just did basic touchup and unsharp mask....poof, done.
I hope the results of the image, is what you were looking for.
