Those leaves are fantastic, best part for me. I also like your population in the far left, looks very natural. The bloom filter you've rendered this with makes those thinner trees on the left look as if they're on the wrong side of the river. Just a suggestion, on your rock out crops, on the steeper angles, maybe make the displacement scale larger, so the displacements on the lower angles look like scree/fallen rocks would help break up your rock structure. Just a thought.
