That looks fantastic. Best looking map i've seen in a long while.
Only piece of criticism I can give, is that in your original shot of the asteroid, the outside looked a little bare, most likely it was just unfinished, but if not add some eyecandy there.

You can get light entities to behave like a spotlight, but they dont produce lightbeams, so I'm guessing its a fancy shader.
