Nice shot but I am distracted by the amount of black in foreground on the left side of the waterway. I copied your picture and put in to PS and did a CM and it lightened up the black and you could see the detail rocks. Good shot but the black in the foreground distracts. With that said 6.
The main fault I see with this picture is that it is too grey and dark for my taste. I guess you should have exposed it a bit more but it should still have been possible to enhance it by using curves and perhaps increasing the saturation a bit. In addittion, a lot of detail is currently hidden in the shadow areas of the picture which could be recovered with the shadow/highlight filter in Photoshop.
I'm also of the opinion that this picture would be much better if you tried to crop it slightly from below and make it a panorama crop. I don't find the foreground to be interesting enough to warrant it's place in the picture. I think I would crop it slightly below the stone in the snow to the left.
In addition, try to convert the picture to B&W instead.
