We cannot see how close she is to which edge, so the suspense you are creating by your title does not really transpire from the photo alone.
Also I'm not sure what the all featureless space to her left is there for, other than that you'd like to put some writing in that space and make this a greeting card, maybe?
I might be too old and too conservative for strange composition such as this one, but I sure don't like the frame cut through fingers or knees...
i agree with the knee thing. if her leg was flat it wouldn't have got cut off. i think this would have been beautiful if she were half and inch to an inch (photosclae not real life) to the left. i love the idea though, and the exposure.
