Okay, I will take a shot at this. You have been very generous with your work, so if my few words help at all, I'm glad to offer them. Before I continue, I should emphasize that I am not a photographer, so I won't pretend to know the technical terms; just offer a critique of the aesthetics as I perceive them.
Natalia is a stunningly beautiful model, a fact helped along by her open-cup bra. I love them for the way they support yet offer up an even better view than full nudity might. The tone of the fabric nicely matches the setting, with the emphasis on grey and beige/brown. The light sets off her skin nicely, though the focus is a tiny bit too soft for my taste. I understand what you were doing here, and it isn't a bad idea; I just feel it resulted in washing out her face and hair a little too much. That is especially important for me, since Natalia adopts such a charming pose; not naive, exactly, but perhaps surprised or confused by something she has heard or seen. It adds a delicious innocence to her sensual appearance.
I like the wood tones (all of my own furniture has a natural look, and my bookshelves have only a polyurethane to enhance the warm glow and protect the wood). Again, the nature of wood adds to the natural feel of this work. Another plus.
Overall, the shot is a little too soft and washed-out, but otherwise well-done. Please thank the model for me, if you will.
