Almost, almost ... if only for a smoother sand-dune. I like the touch of noise presumably added in the sky to match the feel of the sheet/blanket. I think, givem the evident set-up, I might have tried for a more dynamic composition - puttig the little guys less dead centre might add some dynamic. fun shot.
I can see that you put a lot of work into this, probably using added grain to make the blanket (?) look like sand. I think the colors and the processing treatment are interesting, but it doesn't do that much for me otherwise - except I do think it's creative. Wish I could be more constructive!
