Actually, I like it. There are some things I'd tweak about it. Her right leg stabilizes her but it would be much better if instead of that calf being vertical, it was at an angle (aligned with her left leg, establishing more of a diagonal in the shot and with the two calves on the same angle/plane). The white blur (fence?) in the background is a bit distracting and if it was less obvious, that would be good. And while I love windblown hair and the affect it creates, I'd like it if it was off more to the side rather than obscuring part of her face. That said, I like the fact that she has an uncomfortable look to the pose, as if she's growing in to her own body, aware she's sexually attractive yet feeling kind of shy or awkward about it. It goes well with the clothing (which simultaneously screams out "I'm sexy as hell" and "I'm just the girl next door on the farm, I dress like this all the time to go slop the pigs, just a farmer's daughter--that's me alright!"). I like, no, love, the model. I like the concept and you've done a decent job executing it. Yes, it's got an awkward feel to the model but to me, that's part of the charm...it's of a woman who doesn't appear to be dressed up (not glamour, not heels, not obvious makeup) who looks hot yet isn't quite sure how comfortable she is about that. A few small tweaks to the photo (right calf, some misplaced hair, the white background) and I'd love it.
Finally, I've just gotta say that given the pose and your uncertainty about how you feel about it, I love the caption...very clever.
