Hey, we all work in the shadow of giants here, Revenant! Don't compare, just join in! The more in this mixing pot, the better!
I love that sky. I wish I could do clouds half as good, you're well on the way with this one.
And don't edit the clouds, if this is a WIP. Or, at least save this version's settings as a clipfile to use again, they're really nice.
Your terrain here really reminds me of the old TG 0.xx images, get some rocks and a little lateral displacement in there and it'll be a real winner.
