Gah... Okay, I like the expression and the 'moment' here- but the composition is bogus. Is there anyway you could have shot this from the front and had her face on the right-side of the frame? What's bugging me is that while I want to look at her face, my attention is constantly drawn to the awkward shape her arms are making. Should you see this again, I would suggest shooting from the front or shooting from directly behind and zooming in on the details of her hands and the tension on that rope-
It's an interesting motif, it would even have been stronger with a plain background, or at least I'd like to see more contrast between the right lower arm and the door behind it, the contours of your main subject get lost this way. You could make the door and the other thingy less disruptive by adding a transparent white layer and masking the figure of the swimmer. It wouldn't really be 'lying', as the elements would still be there.
