Good: Technically, I like the shot a lot. The lighting is well placed, the focus is crisp and sharp and the grey background makes the picture look professional.
Needs improvement: The pose. I'm not a perfect photographer (by any stretch of the imagination) and often get stuck in similar poses...there's just something...vanilla about it. I don't know...maybe I'm reaching, here. It might look good if she was looking into the camera, or slightly more off to the side.
Anyways, great all around photo. Looking forward to seeing more
