It's a fine shot. Comments follow:
Positive
- Bokeh looks really good, particulary on the center right of the image
- Vellus is well defined with backlighting, giving it a natural appeal
- Depth of field is great, keeps your attention on the face and eyes
Negative
- Something about her left hand doesn't look natural to me. Seems like her thumb is as long as her fingers, which gives it an odd look.
- Lens flare is overdone and the resulting colors distracts from the overall composition
- The softness of her nose does not align with the fine details of her lips.
