good natural portrait, both you and you model should be happy with it. Maybe something other then a white jumper would have helped perhaps a brown or a black?
I think this image needs some more contrast. Everything is sort of the same shade.
Ideally, your model would be slightly lighter and your background slightly darker.
Good use of soft lighting, and beautiful model.
A beautiful and natural image without any over processing or visible touch ups other than perhaps warmth. Her pensive mood/look is also uncontrived. Kudo's for submitting this.
