Night and moving water... frankly speaking I'm having an idea of taking picture light this from some time.
It's nicely done but I got a feeling that this picture is a bit "blueish" if that was your assumption then it's okay.
I like the way how you lit water. I was afraid that after few moments light at the top of the picture will annoy me but it isn't. What disturbs me is strange looks of stones and plants on left side it looks very unnatural like you heavy edited this picture.
Anyway it's quite nice picture but have some flaws (in my opinnion). I really want to see another version of that waterfall.
