A good "story telling" gallery. This is probably my favourite shot in it; the action snatched from a moment in time, the surge of the white water and her gestures all suggesting a great deal of movement that has been frozen. Having her at the far end of the frame with the water taking up the rest is a good piece of composition as well. That must be some long lens that you're using; I noticed one of the other ones at 255mm so it's clearly not the 70-200.
