I like your work. However, while this is technically excellent, I'm not sure that the woman in this environment does anything for me. The very regular grid like effect of the underside of the roof(?) behind the model constrasts with the arching rafters(?), the concrete mass, and the model; the rafter's arch somewhat mimics the shape of the concrete mass, but not too well; the model's arm appears to be propping her in a rather awkward position (and her left hand appears to be somewhat solarized?) - it just doesn't all "mesh" for me.
On the other hand, that model's face is FANTASTIC - lovely, with a timeless expression out of an old Dutch master's oil - that face is - IMO - the real center of this image.
This is all just my unqualified opinion, quite likely worth less than what you're paying for it.
