Great model, pose and lighting. But I find her hands (particularly the left one) and her leg very distracting , pulling my attention away from the rest of the shot.
Could you not clone out her leg and perhaps crop just below her left fingertips to remove some of her right hand which seems to be slightly too near the camera.
Non of the other voters were duly concerned so perhaps it's just me
