Very nice colors and contrast, realistic sand.
But, the men is walking barefoot through the dunes? No way!
Maybe to many palms around the lake?
But that's just my 2 cents...

Yeah, the man is actually wearing sandals, perhaps they can't be seen clearly. Although, some examples of people walking barefoot across sand dunes:

As for the number of palms, an oasis can have only a few, or it can have many. See some examples:
