This is a classic "I don’t know what to do, so let’s try to misuse some furniture-type shot."
It turned out quite well, though.
The key here is the light coming from the side of the body, accentuating the pelvic area, ribs, etc. And I love the abstractness of her left arm.
I purposely let the legs go a little darker, as they seemed to lead the eye down toward the edge of the frame and then out of the picture.
The model is Dovile.
