A pretty scene but not quite as strong an image - the foreground grass at the bottom left is too much in shadow for it to contribute anything more than just a sense of a dark smear. The lighting seems quite flat too - perhaps the early morning or late evening light would be more striking?
I like the frame/comp really well. What turns me off about this is the shadowed land/plants low-left. I think the shot would've worked well if the light was hitting them... If I were there, also I would've taking the shot from maybe a foot off the ground to really get some detail of the stream... with a wide lens to keep the top frame you have...
Tough one - Without the shadowed low-left, I would expect to see this image on a calender, or an outdoors magazine, etc... 5
