C&C: Don't mess with the mood, indeed, but get some more color diversity on the cracked soil, and in the mountains. You don't need the lizard, IMHO, but perhaps some tufts of grass in 1 or 2 patches. And some grime on the house (add PF to color input of default shader, and set small values (0.03/1/0.01, depending on the way the surfaces are mapped).
