I like this image.
It needs some work but I actually like the unorthodox lighting.
If the highlights weren't blown out quite so bad, it would be very nice.
The painterly background is a plus IMO, the overall image has a diffuse glow thing going that would be great if you could fix the highlights.
If you re-shoot this you should try to retain the feeling of the lighting while keeping the highlights within range.
The way the light falls on her hair is what catches my eye. It's just a bit intense.
