Certainly getting there! I played with the shaders for the folliage until it did evil things with purple. Also added the model in the scene! Looks cool, certainly works... but.. it is still way too empty! So, I ended up adding more trees, added some fog, then even some more trees, and finally did some post processing in photoshop for some foreground dust and that yielded the end result you see above! The total render time was approx 15 minutes for 5000x4000 pixels.
