Watching the tide come in..
I like it, but my first thought was the same as jbf's: a different crop showing a bit more water and moving the subject to the left would be better. I don't like what he did with the B&W however. If you can, I'd love to see it re-cropped with more of the actual tide showing.
There is only you and your camera. The limitations in your photography are in yourself, for what we see is what we are.
