Well until the women drop in I'll add my thoughts...
On the techy side of things I like the mono conversion, however I find the blown highlights in the background a distraction.
Emotionally it's harder to get a feeling from it as you've decided to only show a small area of her body and not much of her face. From what is shown I do get the impression of
concentration as she either works out or poses... However, going with the stereotypical views of a woman, she's probably checking to see how good her butt looks in the mirror
