As I said, you don't need my help. :-)
Let me just add that the principle for wild lush grass (as opposed to cropped or cut) is to keep it taller and darker around trees and rocks, in dells and and ditches. Where it is worn, flat and dry it should be flatter and more yellow. To alternate between these two makes for a very natural look. Which is pretty much what you have achieved.
I have some pic examples and grass product brands I use but my web hotel is giving me trouble so I can't post them right now.
