I think that, other than what has been said, it's the clone-army that really breaks things down. After watching the program, "Massive", in action with 3DStudio and Maya in the movies, I think it's unnecessary to try to copy such a grandiose technical achievement with a program like Bryce. I don't mean to discourage you, but it just seems silly to me? Flak's suggestions about randomizing the army are dead-on, but one other thing to remember is that it's ART, and realism in this type of scene is, to be blatant, un-achievable. Don't worry too much over the realism, I'd stick to compositional issues like you mentioned, Hythshade, and see where it goes! It's a great pic, though, with loads of "potential masterpiece" all throughout...
