Overall I feel this piece to have a brilliant impact. I do however feel that her right hand looks awkward. I think if her hand was out of shot similar to her left hand and arm, that the shot would have had a perfect flow to the shape of her body. Possibly a different background too as I feel the model is almost lost in the background, if this was what you were aiming for you've done it perfectly. I would have gone for a darker background or perhaps Dark stockings to help add contrast to the photo without everything seeming to blend and be lost. That's is for the negatives! The positives of this photo far outweigh the negatives. The pose is delicate showing the female form in its true beauty. The lighting is soft and gentle and gives the photo an overall sense of peace and tranquility. The models emotion is perfect dazed look that matches the pose. I took away one star for originality mainly because I have seen photos similar to this on deviantart. This piece to me compliments the female form perfectly and the model looks relaxed and the pose looks natural.
Amazing completion of: lovely skin tone, natural(colors) of makeup, Tones of background, model's top and linen of bed. Model's position/pose, Angle of capture and finally the beauty/attractiveness/sex-appeal of the subject.
