Some quick thoughts?
-The Hoth Rebel tank is pretty awesome, and total mini-rig fodder!
-Colors of costumes as they're seen in documentaries and costume reference photos won't necessarily come across in the completed film. Set lighting and color timing (back in the analog days), now known as digital grading, will distort colors in the final cut of a movie. So what may match costume reference photos may not look very similar to the look of a movie.
-The lightsaber duel practice sessions were pretty awesome. Although I couldn't say for certain if Mark Hammill was sparring with David Prowse or swordmaster Bob Anderson. And funny enough, Hammill was using an Obi-Wan Kenobi lightsaber hilt!
