Ok, this is where I'm at the moment, mid to distance. I think I have my composition mapped out, but thought I would throw this out there to see what people thought.
There's only one external model in this at the moment, and the only image maps are for that one model, a crappy wheat model from Vue. Everything else is native to Terragen.
I'm not too happy about my Altocumulus, it's straight out of the box, ie add mid level 3D volumetric. Will need to work on that a little.
Earth in the foreground has a long way to go yet.
