Kub.

At the first time I really like this photo, analyzing details I have confirmation that it's really good. I like the lighting. The huge amount of light contrasts good with the shirt and the hat.
The skin is almost white (maybe too much) but in the photo it works. Maybe a little more colour on the skin it would be better.
A problem (in my opinion) is the orientation, watching the background seemes the photo is not right (a sensation given also by the white wall on the right).
Another problem is model's hand, it could be great but it was cropped from the image <img src="e.deviantart.net/emoticons/f/f…" width="15" height="15" alt="" title=" (Sad)"/>
Considering the face I really like the light in model's eyes and also hair are great.
I'm not sure about model's expression, it doesn't give me a strong sensation. It's not clear if she smile, she's serious or whatevet.

Nice work in my opinion! <img src="e.deviantart.net/emoticons/s/s…" width="15" height="15" alt="" title=" (Smile)"/>
