This is my end result for the "Creating Procedural Sand Dunes with Blender 2.8" I'm quite happy with how it turned out and look forward to expanding my knowledge in procedural shaders. Thanks for viewing my image if you have any comments please feel free to make them.

and the ripples in the foreground seem to have a nice effect that looks like wind blowing over it.
