The two trees on the left really bothered me, so I scrubbed them out. I liked the original bottom area, but decided it needed to be darker to balance the visual weight of the rocks on the right. I also touched up a few other things, notably the background forest.
Sadly, I think I've lost the feeling of light at the end of the path, and the woods now just looks murky to me. The shadow under the middle clump of foliage on the left looks too straight and too exactly aligned with the shadow above it.
Time to set this aside and let it simmer for a while.
