it definitely works. You are an extremely beautiful woman (sure you have heard that a million times...still true). You are also a very talented model. that expression, well, the entire composition, are extremely well done. Great Job!
while I'll agree to some point that there is a definite quality of sadness to this, I believe that is mainly the feeling of separation from a loved one that is evoking it. great use of lighting, and in keeping it simplistic. beautiful photo!
