Isn't this the same setup as in another thread? It's better if you post a sequence in one thread, so we can more easily follow your progression.
But you're getting there with the setup anyway. Trees are very much better. I would mask the strata shader by a PF, so it's a bit less regular. Also, the shoreline can have a darker color and some shine (color adjust and reflective, no RT, with min and max height). Then some more shrub, grasses maybe....
