Are there too many colors?

I was guessing it was concrete. If so adding expansion joints would help. The "earth" along side the road looks like beach sand as does the hill. I would suggest that if the road is supposed to be concrete add the joints then color the earth (brown, red clay, black topsoil or whatever) on the hill and along the road and vegetate the hill then see what you have before doing anything else to the road. If it's asphalt then it does need a lot more darkening.
