Alright. First I want to say, excellent job. I liek the look and style. I'll just point out a few... inconsistencies?
RED Circle:: Pattern error. in the 3 long circles you can see the grassy layer coming up the edges behind the rocky wall. In the 2 small circles, the corners are missing the closing piece of rocky texture on the top corners.
BLUE Circle: I live the vibrance of the color and grass. see how the vibrant grass looks on the left hand dirt.
ORANGE Circle: Look carefully, the textured edge of that wall has been cut off.
