Excellent!
I absolutely love the lighting in this image, it's very powerful and stands out. The black "light" rays are a very nice touch. The beauty of this piece is the deceiving simplicity of it. Although the only thing I could really critique is the texture on her dress, it's very flat and doesn't conform to her figure. But I do like that you went so far as to disrupt the texture when it came to the folds on her dress.
