Thanks all.
Regarding sharpness you are right. As i said above i don't know why but in this one i preferred the sharpness (i still do
).
Normally i try to use it moderately. But it is hard for sure here.
I wanted it more then normal to make it different as a science fiction image because the science fiction elements are not much here.
Martin, i think it looks more hard because of the highlights too a little. The sun strength was 15.
Detail 0.7, AA 5, Defer ON (v. 4.1.25) V2 clouds.
The noise in the clouds is more from post work from sharpening mostly i think, as i didn't add any. At least not deliberately.
Just to have a better look you can see the original render below.
