Thanks Ken. As for your shot, it's a good photo and the only things I'd say are make sure the tripod is completely still and weighed down, as there is a bit of shake evident. Other than that, possibly lift the shadows a bit? It's a nice cascade and the shutter speed is making the water dreamy looking
