Oooh! I love the washed out color for this shot. Reminds me of a still from an indie movie or something out of Fight Club. Mayara looks like she's perfectly cast in the movie - lithe, beautiful and pensive.
I think the overall effect could be enhanced if you flattened the sharpening of the pebbly pillar (I don't think you PS sharpened, but the sharp pebbles distract from the overall soft feel of the photo).
