I especially like the mid section; stones and shrub/grass are really good. Are they fake stones or a rock pop?
C&C: I would perhaps add one more species of tree for diversity, reduce the ruggedness of the mountain behind, and (very important) increase detail in the under water area (inside render node, up subdiv level to maybe 0.8 or so, but increases render time). And perhaps add a line of wetness/darkness/ algae at waterline.
