Here's a few ideas for small ideas for ROTJ:

-Have some body parts fly off when Luke's lightsabre hits people on Jabba's sail barge

-Maybe some stragglers jump off before it explodes

-Jawas with the Banthas in the SE shot shot...

-...who come and watch the explosion from a distance.

-the briefing scene should be prequel-ized: darkened, some lights moving etc.

-the Home One hanger looks a little cramped

I agree with the idea of the space battle being closer to the throne room, after all Palpatine tells Luke to watch but he's too far to see anything!

Please don't touch the Tyderium shuttle, its my favorite craft in the movie!
