heya; neat! not sure how to make a steamy jungle, though... have you tried doing fog that gathers at high altitude instead of low? or maybe you need some big spheres in the scene with a few wispy thing clouds on them. some tendrils in amongst everything, you know? your vegetation is looking a bit too large... if this is supposed to be a zigguraut temple. either that, or it is too close to the camera. the scale right now makes it look like a model, maybe 6 inches high. you could probably fix this if you put the camera looking up at it, and maybe play with changing the focal length.
