Thanks! Definitely not the final one though.

I don't know if it's very visible, but the foreground is on top of a
plateau, thus where edge of the plateau is, the distance to the ground (and
the amount of fog looked through) changes abruptly.

There are no dunes here. It's supposed to be rock all over! As I said, my
texturing skills are not that good...

Probably. I'll try a more sandy look next time.

Thanks!

That depends on your point of view.  The normals are large scale in
contrast to small scale structures you would use for sand or gravel and
they are strong enough to cause shadows if they were not only normal
perturbations.

Not if you add some turbulence (or use less turbulence than for the
heightfield).
