This is a monochromatic studio portrait of Keira, a professional figure model.
Usually, as I note in Creative Portraits, I prefer to use the camera to show someone’s eyes when I photograph them—after all, the eyes are the window of the soul. However, with this photo, I think having Keira’s gaze demurely turned downwards works, because the demure posture contrasts so strongly with the beautiful sensuousness of her naked body.
