I think this one is lacking something Jon?
Maybe just for this one, the angle doesn't work. If it was taken head on, it looks like you might have some nice vertical and horizontal lines? But it's hard to tell from this angle.
Looks like it was a long way down - makes me feel a bit giddy. I like the composition, it's tricky to work out exactly what's going on, but the sense of motion in the water and perspective of the rocks is interesting.
