The rule of thirds is too simplistic and as this proves, not only can, but must be broken. A rule of more universal application (not just in art) is the Golden Mean. But one would simply choose the best composition by gut feeling, at least I do. It is a matter of having a 'good eye' rather than being weighted down by a bunch of rules. Of course one has to know the rules first in order to decide to break them - like the inane art teacher rules of grade school (color between the lines).
Check your "Be sure to click on the image to view full screen!" - it is a broken link. The proper URL would be this, for Full Screen - it works every time and I use it often. Going to the large size, I feel for your model: she must have been freezing her ass off in the drizzle rain, and looking closely, one can see her goosebumps.
