cut some of the forground brush, looks oof anyway just distracting. put your focus point closer. i am guessing you focused straight across the pond. Move it back like half half way, a third off your shore. only not sure what mode you shot this in, but open it up. then keep it at f14 or something with your focus. nearer. The bench does not need a focus point directed straight at it, as it is part of the over all scene.
just guessing here. i can barely see this, cant see it up close. Might have made more sense in color and we could view it easier. The gray in the foreground just seems to all go togther...
