Very nice; a couple of issues I see. (1) The skin temperature seems somewhat too warm; and (2) you seem to have missed focus. Your DoF was so thin thin that the focus appears to be about 6" in front of her face.
The Exif says it was on a f/1.4 85mm lens, with the settings at 1/160 sec, f/1.8, ISO 100. You need to drop your shutter speed a little, up your ISO, and close your aperture down to around 5.6-8.
