There was so many possibilities for the colour toning side on this, but went with something that i thought suited her skin tone well.

What i did...
Cleaned up the skin through a series of Micro dodging and Burning, Frequency Separation, and Luminosity painting.
Removed the lil hairs on her shirt. Also got rid of the logo on the jeans as it kept catching my eye. Also got rid of some of her fly away hairs.
General D&B, including the eyes. Added colour and saturation to make them pop a lil more.
Cropped slightly. Selective sharpening to the eyes.
Colour toning using curves, and gradient maps.
And added some grain to give it a more filmic look.
