Many thanks all for the compliments.
Amazingly, I just threw this one together, mainly to see what I could do "quickly" with stock terrains - which is why the mountain surfaces lack detail. Then I saw some potential, but kept the "get this one together as fast as possible" idea, as I think this can build skill in a lot of cases. The clouds and moon are simple clip files I had pre made, so they were added very quickly.
@JimB: The clouds are mapped using the plan Y method. In order to create the custom mask, I took a quick "snapshot" of the scene with the camera directly above the peak, making sure the top of the image was north, the bottom south, the left west, and the east right. It didn't require high detail, I just needed to know where the peak was in the image. I then took this image into photoshop, added a new layer and literally "painted" a black and white image mask where I wanted the clouds to be. Honestly, it only took about 10 minutes to do the entire thing. Then I brought this mask back into TG2 and used it as a blend shader for the cloud fractals. I've had success with this method in the past, and it worked well again this time. Building this procedurally would have been extremely difficult if not impossible, and would have taken ages.
I'm not sure if I'll re-do this image again, but if I do, I'll definitely add more detail to the surfaces, and retweak the foliage a bit.
