great image, Peter. You are using the bushes very well, they add a lot to the scene. The grass distribution does look a bit too scattered though.
Also I agree with Dandelo about the lighting. You are giving away a lot with that "shy" lighting. Brighter, more saturation, and maybe have to add contrast as well - but all this is just a matter of optimizing the postwork.
Anyway, I like the story of that scene, definitely interesting.
cheers,
