Hey everyone, its been a while since i had time to really try out stuff in my TG2

here's a scene im trying to get looking right.. and the results so far im fairly happy with.. It just seems bland to me and I need suggestions for things I can improve.
I really want to get better defined Rock on the mountains, but ive been finding this very difficult to do.
Render settings are as follows
AA: 5
Detail .6
GI: 2 (overall) No GI padding
Resolution 1280 x 720
Render Time: 45 Minutes
Atmosphere 1: 20 Samples
Atmosphere 2: 8 Samples
Clouds are all on quality 1
I wonder though, Ive been trying to get swirling clouds around the planet.. but nothing I do with projection works. Im afraid I need some help in this regard.. Ive pretty much given up hope that it can even be done.
