Great use of light has resulted in a high-contrast image that is pleasing to the eye. My only request next time would be for a larger image to really show off how good the photo is.
A very interesting try at using a single, strong directed light to highlight your subject. It adds a harshness and seems to fit the feeling that something awful has happened. The shadow behind the subject is a little distracting and backlighting from above and behind to the back of the head might add more interest to the composition.
