Really I love it. It doesn't match with your overall style, though. Meaning if you attempted to add in a character it would seem fairly awkward unless it was in the same painty style which if practiced would look really good in your style. One thing you do need to pay more mind to, though, is cast shadows. Your lighting is pretty solid as is your shading except the lack of cast shadows x3 like the trees shadow on the ground should be much darker and the shadow on the top left of each layer of the tree (the top be exempt from this of course) due to the layer above it. You are actually at a pretty good start x3
