Very nice, I really enjoy seeing the progress on this. It briefly reminds me of Fool's work. Sorry for comparing you to another, but it's intended as a compliment.
A few things that would really help improve this piece is to play with you palette. I think it needs a bit more contrast and some cleaning up of noise areas. The grass could easily become shapes instead of noisy/distracting/messy ... clusters.
Atmospheric perspective is a tool you should at least try to use. It'll give this piece true depth.
Fool uses it quite a bit in scenes.
Hope to see more of this and more from you.
