I don't like this as much as your last one, but it does have potential. I think it has a cardboard cutout feel to it now. It's very 2-dimensional since the shading is flat with highlights everywhere and no real shadows. Just adding shadows on the rocks cast by the trees and plants would help a lot. You're also using more colors than you really need for something like this, I think, and the different ramps could use some more variation in hue. The green AA on the branches looks a bit out of place. You could also make the trees look more natural by adding some random leaves scattered around the crowns, and the rocks could be darker and more angular. Keep up the good work, and let me know if you'd like me to elaborate on something.
