with the white stockings on the satin it almost looks like she is melting or fusing into the background. I think with a little more white, perhaps some lace gloves or some velvet trim/ rabbit fur over the shoulders or lace ribbons in her hair the effect would be reached. with more white wall (or photoshop). I understand that may not be your medium Im not trying to critique, that's just what came to my mind when I viewed this. Beautiful work.
