I appreciate your attempt. You had scopes to make it more interesting. But the selection of slow shutter speed makes the photograph very eye-catching. By shooting wider frame you could have been able to cover entire waterfall and it would have also left more space at the top which would have made the photograph complete. In current composition the natural frame of tree branches makes the photograph attractive. When you shoot at such place next, try to experiment with focal length and exposure to get the best result.
