The shaded sides of the dunes seem too dark, especially since there should be
quite a bit of scattered light from that cloud cover.
Perhaps you should try placing the grass in some slope/altitude dependant
pattern (although you might have to do this with trace, I'm not sure if the
"slope" pattern would work with eval_pigment). A line of grass running straight
across a dune seems a bit strange to me.
