Bingowings, thanks for the review. I'm on holiday for the week in tropical Bournemouth, so can't do a detailed breakdown of your points right now, but when I get back home I'll go through them. Lots of great suggestions, for which I'm grateful.
And regarding your last paragraph, that's exactly my intention for this edit: I don't have any special effects skills (as you can now attest) but hopefully these ideas can someday become part of a definitive ROTJ edit. There's definitely a decent, though not great, movie to be found in here somewhere.
