The tundra around Whiterun always bothered me with its odd red and yellow splodges, grass having an unpleasant yellow tint, some things are just plain too bright and some use fake lighting that looks pretty bad. I've tweaked colour and contrast of just seven diffuse textures based on cleaned SE textures at standard resolution.
