Reminds me of "Hotel California". Nice crop. Love the reflection and the fact that the background is black but clearly there's something better she's looking at.
Very nice! It has that sense of fashion model about it...glamorous. I do think, however, that lighting could be improved a in two places. Some reflected fill light could ease the harsh shadow cast by the nose. And somehow back-lighting to prevent the second half of the glasses from merging with the void...perhaps it would have only taken a half step into the light toward the camera to pull up that detail. Even so, the image has immediate impact. The colors are a delight. The expression serious without being overly self-conscious. Nicely done!
