--New shots of the Falcon and TIES in the asteroids?
--Shots of Luke's X-wing entering and exiting hyperspace (especially after he says "we're not regrouping with the others" etc etc)
--Adding a planet to the scenes with the rebel fleet at the end of the movie (Sullust, maybe?)
--Adding some of those hot-air balloon thingys and tibanna gas refineries to the initial far-away reveal of Cloud City with approaching Falcon
--Improvising the sunrise-from-space effects when you see the Falcon leaving Bespin being chased by TIEs
--Shots of the X-Wing inside the Dagobah atmosphere (from outside)
--I'd sure like to see those Tauntauns running a bit faster; the stop-motion makes it all look like big steps, slow speed.
--Maybe you should test out animating CGI characters to replace the stop-motion tauntaun shots.... just a concept, lol. Could maybe prepare you for ROTJ (especially if you will want to add extra Ewoks there lol)
Could you take these into consideration?
