You have a beautiful model to work with. Overall, I like the image you made. The only thing I would do different is to use the light to shift the emphasis more to her face. Rather than just tell you what I would do, I have done a quick and rough edit to your image (hopefully you don't mind). I did three minor edits:
I brightened the eyes just a bit.
I lightened the face some.
I did a light vignette to knock down the brightness of the white shirt since the brightest part of an image tends to draw the eyes and your model's face is too nice to not be the focus.
Keep up the good work.
