Are the plants and trees used natural, on the other hand the distribution is to be re-examined, not grass under the trees, a cover of the very important mountain, too important by trees, whereas the mountain behind is naked? An image to be worked again it seems to me and which will be only better. Perhaps is necessary it to add other species of trees?
Grass under the trees, removes those on the mountain and adds one or two species in your forest that should much better be!
