I always like it when I see a black and white image. One can express so much through black tones, white tones and especially grey tones and bring a totally different atmosphere beyond color.
I think the mood of the photo is created here by the white of the waterfall, I can almost see and hear it falling.
The framing is good, the white parts of the image showing the viewer where to look at. It's like scanning through the photo, given the virtual lines.
It's just me, but I would have wanted to see this a little wider.
