Look at the texture used in 'isocacti.pov' that is in the scenes directory
of POV-Ray. That would do the trick I think. The secret is 'micro normals'
but also even more a pigment_ or color_map with enough contrast, very
strongly scaled down.
By the way: concerning the tree shadows in your image: try to make the tree
cast shadows only on the sand, not on the background (using light_group).
That might be an interesting approach.
