Very nice shot of a beautiful woman.
Her clothes are dark and there's nothing in the background, so her face is the only thing to look at (which, in and of itself, isn't a bad thing.) Because the lighting is offset and she's facing down, her nose might appear unfairly prominent. I think I might have her raise her head a little, or bring the lighting closer to the center, or use a fill flash, something to make the shadow of her nose less noticeable.
I tried adjusting the brightness, and might have lightened it a little (perhaps just enough to see somedetail in her top), but I like that it's a darkish image. It makes her beautiful brown eyes stand out.
But all of this is really picking nits. She's beautiful, and you captured her image very well.
