I think you're misunderstanding the shot then, it's not actually a portrait IMO, it's more of a landscape; kind of like a Monet piece with the subject serving as a point of contrast to the larger scheme, almost like a tree blossoming alonside a dirt path weaving through a meadow alongside a hillock.
The intended contrast seems similar to this painting:

And the model's place in the image seems to serve a similar purpose to these subjects:

Your interpretation seems to be based on some expectation of a pinup style shot with the landscape supporting the model, but I think it's a landscape shot with the model providing a focused point of contrast.
I guess we'll agree to disagree, I see a stylistic landscape, y'all see a botched portrait.
