Wow, that's an improvement. The latest one is really great. The only thing that looks a bit strange to me is the lighting. May I ask why you use two suns? The lighting is quite flat. I'd love to see your image with only one sun and a little more contrast. You could also try a fill light setup instead of the environment light (in this case don't forget to disable GI).
In my opinion people are too often tempted to use two almost equally bright suns instead of one to brighten up the scene. The fill light setup does of course the same but a lot more subtle.
All in all a fantastic image. It looks like a place about one kilometer from where I live (except the mountains).
