I really like this one too! It has a very natural feel but at the same time a slight "dreamy" feel past the foreground trees, which is a nice balance. I agree a little color variation would be good, but not strictly necessary. The only other thing is it's a bit noisy, probably due to path tracing with lower AA. Of course it would be longer render time to remove it, so it's a hard choice without newer/better hardware. Maybe when your other machine gets fixed you can revisit this at higher quality, but in the meantime it's quite nice!
