I really like this one. There are lots of interesting parts. I like the frozen water against the falling water. The layer of ice that appears to be hanging is wonderful! You have darks and lights, so I think B+W would work, but the colors, too, are very pleasing to my eye.
My only question is the upper right hand corner and the bit along that top with the snow and the dark line of the crack. It seems just a bit out of place with the ice and water. But. I am not sure what can be don about it without cropping it out, or just clone or widen the ice. Suppose you do crop. You would lose a good portion of the "hanging ice". Take a look and see if maybe it would bring more attention to the water.
BTW Where is an easy way you could extend the ice in PS with the content aware patch tool. I will look it up for you. Basically you would lasso select the ice and use the extend mode.
