To start, I would like to say this is a wonderful shot and your model is rather beautiful. ^^
The vision in this picture is great, clearly focusing on the model without completely blocking out the back round.
This picture's originality is a bit off, for I have seen this pose many a picture. However, you have used it well in this piece.
I really have to give you credit on your technique and setting choice. Like I said before, you chose a wonderful model and you focused on her properly without cutting out the back round entirely. The back round is humble. Quiet and not busy, something that many do not chose in a back round.
Overall, I enjoyed looking over this picture. Great job
