The landscape is very nice. I love this.
The haze is a bit of a problem, but you could adjust that by applying a maximum clarify level and then a bold contrast. And then readjust the colors. That would make it a entirely different photo. Maybe you want to try and see if you like the effect.
I love the autumn colors across the valley and the framing by the tree in the foreground. This must have been spectacular to see in person! I'd have to agree with Paul, though, that the haze detracts from it a little. If you are able to rework it a bit, I'd love to see a reposting!
