A little dull with lack of an obvious subject. Not all images require one particular subject but a person in the picture or even a rock in the foreground would have helped. The falls does look nice but by themselves doesn't have enough presence IMO. 5
It looks like a wonderful spot, but there's so much foreground that seems unnecessary to the picture. I'd like to see more of the falls and the movement of the water.
I'm not caring for this I'm afraid. I think the biggest problem, for me, is in the composition. The main subject seems to be intended to be the waterfall, which is a thin strip, centered in the frame, partially hidden by the field in the foreground. That field is the brightest and largest thing in the frame and it is what attracts the eye instead of the waterfall. A closer view of this waterfall, perhaps at an angle of from river level, might have been quite nice.
