Hi again,
Looking good!
Here are some purely CG crits this time. First the grass looks a bit too bluish, and the stones look a bit too reddish. The stone texture and shape can use some improvement. They almost look like they have a toon shader due to the dark outlines around every stone. They also look too much like perfect rectangles, they need some depth variation from displacement maps or something.
One thing that I think will improve overall quality a lot is using some mild DOF because at the moment it looks a bit fake to have everything from the far distant geometry to the up close all being in perfect focus. This hurts the grass especially because it betrays the CG nature of it which would look more realistic with a slight blurring. Just going over this with a blur brush in certain areas made it look a lot more real to me.
