I like this photo, and the title. :) I think it would have been enhanced quite a bit if you had cropped off the yellow backlighting on the right and the right half of her head. This would draw our attention much more to her eyes and secondly to her hands/camera. As far as darkening... mostly the ear and earing are a bit distracting; some adjustments might help those features to not be as outstanding. Also the crop would help here too, imo, because at the moment her earing is at one of those rule of thirds intersections and cropping the right would move it well away from there.
Nice picture although you should have made it a little darker to avoid so much details in the woman.... but, if I almost close my eyes when watching it, then it is very nice... (could leave some details on the hands and camera) - IMHO... good luck :o)
nice colors, but the subject is not a complete silouette. there is definetly some visible detail. this actually works better for me as a picture than it would have if the subject WAS completely black, because then the silouette would have been too big. 7
