That was kinda my thoughts too when I saw them. Minimal processing here, just 1 little saturation boost and a little sharpening. No cropping, cloning, etc. That sand was just colorful
I like the rocks and sand picture it has a Peter Lik kind of look to it. Bob you should visit one of his stores here in Vegas to get an idea of some thing you could do with Photography. His photos framed are simply unreal and you have to see them in person to understand.
