Raj - Another magnificent image. I must say that she really does look 12 in your Facebook image where you are sitting beside her. No complaints about the skin tones this time.
I'm starting to wonder about your screen setup as a lot of your images are coming through looking rather underexposed, with the histogram suggesting blocked shadow detail. Have you calibrated and profiled your computer screen? I recalibrated and reprofiled mine just over a week ago and it is set up to the standard 120 cd/m2.
When I pull up a histogram on the image you posted, all the data is crammed into the left hand side of the histogram. I'm pretty sure you are looking at a darker, moodier look, this is not the way to get it. Look at the whites of the girl's eyes. They are gray, not white. This is probably not where you want to be with this shot. Again, expose correctly adjust the white points and black points accordingly and vary the level by using the middle slider. That way you can get the moody look you want without sacrificing the light tones or dark tones. You want the whites of the eyes to look white, but not too white so that they look spooky.
(Note: This is a screen capture so the colours are off a bit)
Other than playing with the levels, the other thing I noticed is the lack of detail in her eyes, lips and eyebrows. I did some localized in-process sharpening here so as to not touch the work you did on her skin. I added a vignette to darken the background a bit, but did it in such a way that her face was not touched.
You've probably noticed, I crop a bit more aggressively than you do, so the first one is the way I would crop the image and the second one is your crop with my edits.
As for the edits themselves; here is what I did:
(Again poor colour due to screen capture process)
Top layer - this is where I built the vignette and ensured that the girl's face was not affected by the vignette.
2nd layer from the top - this is the levels adjustment layer and you can see how I positioned all three sliders.
3rd layer from the top - here I duplicated the bottom layer and used the Unsharp Mask settings that are shown. I applied a layer mask to hid the changes (body of the mask is black) and then painted out the eyes and mouth in white to reveal the sharpened image locally.
Bottom layer = Raj's original image with NO changes.
