I love the exposure and the colors. The subject matter is very great. The little bit of blue sky peeking through is quite intriguing. The layering of the composition is really interesting--silhouetted trees, silhouetted points in late, far mountains, and very far mountains.
I'm defintely with the previous poster...there is a lot to love about this image...really great! Some options, I would look at it with some crop adjustments - the tree on left is an issue for me as well...if there was a little more of the left hand side of the view available that might be better...a little more tree...and a little more dark shoreline to balance that on right. Lastly I would look at it with a fractional amount cropped off the top...1/20th"...for me there is a lot of dark nearly monotonal gray...against the very very subtle image elements.
