Hey wow, that is a fantastic improvement in my eyes, I'm impressed. The terrain fades nicely and you kept the dark values up front - and the main thing - you simplified the composition so that everything reads well and in perspective. This is fundamentally a much, much nicer composition. Awesome work, I hope you think it's a better peice too?

The only thing I'd want to change at this stage is add some occlusion shadows to the bushes in the foreground - because of the shadow underneath the clouds, my brain tells me the sun is overhead, so the bushes casting a shadow underneath will ground them and stop making them look like they're floating. Great improvement in all areas nonetheless.
