Environments from the "break"

I have a couple things. Yesterday, I did a couple environment concepts and tried modeling them out for a better camera shot. Top image is my favorite, and very work in progress. I wanted the structure to look like some sort of factory/temple.

I started out with some basic shapes, and then...played around and painted it! I was practicing scale with massive shapes. I'd imagine these fell from the planets orbit...maybe they are large satellites or broken gateways..I'd like to explore this concept more!

This one I'm just documenting on the blog...it's garbage...and it has potential, but needs work, and maybe a new camera angle. Comments and crits as always!
