Lovely shot Ken, but there's something very strange going on with the water. You seem to view the distant water at a quite sharp angle with little reflection detail of the sky, then suddenly, just this side of those stones, it's as though there's a waterfall, or the water is suddenly sloping towards you, and at the same time you get major reflection detail from the sky.
Looking at the banks, there clearly isn't a waterfall, it appears to be just some strange optical thing which really mars what could have been a
great shot.
