This is a nice update everything is coming together. I love the addition of the little pond/stream.
Though I have one concern, why are those bushes internal shadows so soft compared to the scene? I feel they should have richer internal shadowing, especially with PT. Perhaps the opacity has been adjusted a little too much?
I also agree with Oshyan about the sky. While simplistic, it's superbly realistic, especially for the evening/morning setting you're capturing. Well done.
