Here is my first "correct" rendering.
Just a modification of contrast and colors by post processing.
Pretty damned good. Sure you can work on more subtle aspects, like getting really small displacements in your soft sand texture, maybe just colour. Or getting your tree to GI up it's colour a little, but I guess the textures didn't work out on this try. But you've got some nice outcrop distribution on the flats, your hills look subtle, and your stratus has soom nice curves to it. I'm not sure if you're using the free version, but this could do with a more letterbox aspect to it imo.
Manu49 , it is a good first render :)
Hetzen said all what i think ...
