She looks gift wrapped, but it appears someone already took a peek to see what they were getting.
Excellent use of light, or the lack of light. I'd say the right amount of highlight. The amount of shadow makes this seem as a real moment in the sense of: you could easily remove the camera and there would just be a man (or woman) sitting there anticipating the next move. I am not sure if that is what you intended.
If there was something I would like to see different in this image is perhaps have the window blind down to have the light cut in slices. There would have to be a good amount of distance though or the shadows would be harsh and note quite as diffused.
As always, it is one hell of a shot. I figured I'd try the critique thing.
I enjoy this a lot. From the bars of light cast on the bedside table, to the seemingly empty space of her high waisted skirt. Actually, that is the thing that draws me in the most. It seems mysterious, though it looks like a simple slip being pulled down. It's an organic block of black, made erotic with the shape of her upper body, the lace trim, the stockings, and single strap on her leg. Her left thigh seems oddly shiny, but I like the lighting on the rest of her body. The softness of the shadows and curves contrast the rigid bars on the bed and bedside table.
