What a beautiful landscape! This looks like something that should be on a postcard, not hidden away in a gallery.
On the technical aspect, I'm unhappy with the horizon fog and some light fog points on the darker right side. The balance is a little off, but overall I think it's just superb.
The depth and distance would probably be more accentuated without the close-up tree line on the immediate left side framing the photo. I think if the frame had been cropped just a few more pixels on the left, it would have improved this and been less distracting to the overall photograph.
Though overall I like it and feel it's a well composed photograph. Congrats!
