[Chris Saper]

My congratulations to you as well!

I think this is a successfully balanced composition, and well-executed piece, so my comments are really fine-tuning thoughts. In concert with theedge related comments you hav ealready received, I think that softening the outer edge of the arm on our right, where it joins the dedge of the surface, would help cement the viewer's visual pattern, and not tempt a preemptory look in an area you don't want.

There is a tangent in your portrait, where the silhouette of the lower cheek on our right joins the blouse. This would be an easy modification, softening both edges, and making the shapes overlap instead of meet.
