Is that mist or cloud - the bright patch in front of the far side of the gorge? Very effective behind the dark overhang.
And the long exposure working its wonders on the flowing/falling water.
That large boulder teetering on the edge of the fall adds a dynamic.
The soft underpinning of the image by the ferns.
Sorry that I have to "take half a point off" for the small branch that stands in the near foreground and in front of the leftmost stream of the falls. It's a distraction, to my eye.
