I've wanted to do a scene like this for years, so finally scraping together enough skill to do a basic fly around like this was a hoot.
I'd like to add better camera moves. That Battlestar Gallactica fast zoom/pan camera work rocks but I haven't a clue how to keyframe that style of camera..
One final thing I'm proud of, there are no fake lights illuminating the ships. I really hate that in movies where spaceships are beautifully light, but they're in a mostly black vacuum of space with a single light source from the sun. I'm looking at you Star Trek :P
