This is one of the photographs that remind me that black and white landscapes can be extremely beautiful. The way you have achieved sharpness from near to far is a real technical achievement, and the slow shutter speed to blur the movement of the flowing water and the clouds up in the sky must also be considered as one. Speaking of the river, it works as a wonderful tool to lead up the viewers' eyes deep in to the scene you captured. The blurred sky is a brilliant way of preserving the viewers' attention on the mountains in the background. If the clouds would've been tack sharp, they might have overwhelmed the mountains as the main subject. The contrast is brilliant, and nothing is either too dark or too bright.
