CC please. Our turf artist, Smiker is working on the cliffs to make them fit better together.
I agree with Maggeh. You've got a really good consistent style, which can't be simple as I think you've got 2 or 3 people working on your art.
It does look, tho, like you've got a horizontal band on the tiles where two cliffsides (the south facing sides) come together. I really like the two shades of grass you've got and how the work together. Good idea.
The only other crits/suggestions are simply refinements: You could add some alternate textures to break up the cliffs. You could also break up the grid-diness of the turfs by using less straight lines and more connecting curves.
