When I think 'boudoir', sensuality is the first thought that springs to my mind. Secondly is that of a woman in control of her sensuality. Third is lighting to accentuate her blessed curves. On that note.......
You have a very imposing PoV.
Her pose only contributes to this feeling of domination. The arms outstretched and overhead gives a victims look rather than a sensual one. The position of the hands, with palms up, suggests more manly than feminine. This position is also causing skin creases around her neck and shoulder.
The position of her head (chin in particular) provides a large area on the side of her face that lacks facial features, such as the jawline. The hair is a mess and the spikey ends, again, contribute to victim.
The sheet being pulled up so close to her neckline gives an impression that she is not comfortable or has yet to rise out of bed. The bit that is running up the left side of her head should've been tucked away.
I think it's because of the torso and upper body positioning, but her legs look very short compared to the rest of her body.
The lighting is flat and does nothing to accentuate her body and curves. There are virtually no shadows. There is no separation of her to the background, which gives the 'floating in air' look.
All that being said...... kudos to the two of you. It's not a terrible shot, but can be improved upon. Do some rummaging around the net for boudoir posing and lighting. You'll get there.
Just my 2¢.
