Gordon it's looking good, lovely job on the head and neck. It has some structural problems with that near shoulder coming too far toward the viewer. Where the clavicle meets the acromion process looks about right so the shoulder should start to drop from there. Also as David points out the sternum doesn't look quite like that she must have been a bony model.
I know you are a careful drawer and I wonder if you lose sight of the whole because of the attention to details?
The last 60 plates of the Bargue Drawing Course if you can find them online are worth copying to give you a better structural feel of the body.
