Hi there,
a new one...

C&C welcome.
I think the small stones on the middle dune look to regular. Try a distribution shader in the blend by shader of the fake stone layer. Check the fractal break up. Reduce the coverage to 0.35 +/-, then increase the density of the fake stone layer. Now you can play around with the measure tool to set the fractal break up scales. These scale take some tweaking, crop render a section to see how things look.
Great clouds and POV. For me, the colour contrast between terrain and fake stones is too sharp - it makes the stones seem artificial.
I like it but I see a couple of things I'm not too keen on...
The one bird is a little unlikely, unless, that is what you were going for. That's only minor, whatever the case.
Also, the stones, especially the large ones, have a little too high displacement levels, they seem extremely spikey to me.
I think you unchecked 'do ray traced shadows' in the render node, aswell, else there would be shadows behind the rocks, your sun is directly in front of the camera but this doesn't translate in the shadows of the rocks/terrain.
Or, maybe you have some back-lighting, or some extremely high GI strength on surfaces cancelling out these shadows? It needs a little shadowing, is all.
The clouds seem a little stretched on the Z aswell but that just seems to be a camera/aspect ratio setting, I think, not anything to do with the cloud fractals, unless they are warped a bit much.
Nice, though, I like the basis. T'is good! :)
Thanks guys! I am not really happy how the distribution of the small stones in the middle worked out, but well... I will go on to other projects I guess :D I used only one bird to emphasize the loneliness of this place. I used a light source in front of the camera to lighten it up. That is why there are no shadows.
