Different indeed, and very fast

So where do you want to take this? For a full hillside environment, I'd add more species of grass (etc), more displacement in the rocks, and some gravel/sand or bare rock between the loose rocks. The light, POV and focal blur are already very nice.
One hint for the rocks, add a small scale fractal warp shader between the power fractal (for color and displacement) and the texture input of the fake stones, and play with the settings.
