Sand is - at the same time - easy and complicated to do. Imo, your renders 
look well. I suppose that the technique used depends on the type of scene 
one wants to build and the effect one wants to convey. This means that there 
is no definitive solution, or so I experienced myself. Using crand, like 
Mark says, can help, although I do not particularly like it. Perhaps using 
more contrast between the "grain" colors gives even better results. That, of 
course, depends on the type of sand one wants to render.
