Sanj, it has less color saturation than I like, but the overall composition works pretty well. I bet you love that Zeiss lens!
As for the sky being blown out...I'm not sure 2 more stops would have gotten it all, but it wouldn't have hurt (also unsure why we'd speculate about it unless someone is suggesting a D800...which I would not...and the D800 isn't quite 2 extra stops anyway, is it?). The sky isn't all that important to this composition, though. It's just the way it gets blown out, around the edges of the trees, is not all that pleasant.
I doubt I could have done any better, but what I would have done, would probably be composed differently. I can only guess.
I do like the wide cinemascope aspect, it works well! Kind of looks like a still from a video...I know you're a cinematographer, so that is likely where you are coming from here. I sympathize, I've wanted to make movies since I was a kid!
