Composition wise, I find the branches on the left hand side, bottom, to be intrusive. They distract from the flow of the pole going into the water.
I like the reflection of the clouds in the water, I would try to bring it out a bit more, perhaps with a local contrast boost.
I would not change the saturation in the trees, I like the somewhat subdued earth-greens that hint of approaching winter. I think the greens complement the earthy-browns quite well.
