My attempt at trying for a stormy mood. Thanks to Matt who pointed out the obvious to the clueless about the cloud rendering issue I had. Please excuse the cheesy postworked lightning bolt, best I could do for the time being. And the outcrop? Looks to me to a petrified Jabba the Hut. Sometimes it's only a roll of the dice with terrain features. But there you go.
Thanks for any suggestions, as always!
