This is easily my favorite of your work to date. Here's a few nits.
#1, is it just me or is that outfit everywhere this year? That's more of a question than a nit.
#2, I'd agree about the background being distracting, but for a different reason, I think the license plates don't fit with the antiquey/rustic feel of the set, maybe if the paltes were older theyd fit in better.
#3 There's a wierd bulge on her butt, underwear lines maybe? Love the way her hair is blowing, and great expression.
#4 Love the way the lingerie, jewelery, and set dressing all fit together. Maybe a little tighter crop over her head and on the left of the photo.
Here's another general question. Is the hair over the boobs pose becoming cliche? I seem to have seen that a lot recently.
The man who said climbing Olympus Mons was impossible was a quitter.
