Suggestion: Get closer on the subject. You obviously want to display the water fall there so zoom closer on it. That will make it the focal point. Also try getting at better angles such as lower to the ground or shooting low and from one side. It helps emphasize the subject and sometimes exaggerate the size making things more interesting.
No offence, but that looks like you walked by and said "hey cool" brought the camera to your eye, snapped the picture and kept walking.
Always room to grow man, and please take anyones words here with a teaching attitude. We are all to invested in photography to just flame people.
