Nice walking profile, and the legs just pop against the beautiful blue water (not sure if those legs are a bit too saturated or not...and I'd tone down the sheen on the front one). In a perfect world the front foot would have been a bit higher and visible. The edges seem a bit jagged, perhaps a sharpening and/or resizing issue. Good comp!
I like the composition and the pose. I think similarly to Daniel on this - it seems a little sparkly - I suspect it is sharpened a little too much and perhaps reduce the highlights a little, I think this would improve the image a little:)
