From a technical aspect, I think everything about this picture is very nearly pitch perfect. From the lighting, to the pose, to the choice of such an exotic model, everything works about as well as it possibly could. Even the small choices: like having the hair drape over the side of the body that has more lighting, or having the only visible clothing be the black stockings she's wearing) were the right choices. Overall, the image is quite original and has a rather strong impact on the viewer. The way the sword is held over the shoulder and behind the neck gives the viewer lots of material for generating intriguing fantasies.
