Just think logically, grass clumps grow near/against objects, so add some clumpage against the house.
Big fields look butt ugly on graal, choose any theme BUT fields *shiver*
As you can see.
My lawn - no thick patches of grass, because its MY lawn and I'm going to keep it relatively clean.
Out of that is left to be mangled and ratted.
I added some water bottom left for good balance, and for general logic (urgh I'm thursty!)
Also notice how there is a thick line of grass along the trees, it's only natural really.
I love that house <3
