Gee, I always just watched and thought, there's the rebel fleet out in space, they got chased out of their base and where the heck are they going to go from there? At the end of IV they had a base at least, and had taken out the Death Star. I didn't think, that's not even their galaxy (how would anyone even know this watching the movies without an external agent telling them that?), that's a star forming, I just thought, they're in space....

All of the movies move from light to darkness but some of the other ones have some light that returns at the very end (throne room in Ep IV) but this one is elevator that only goes down. No resolution to Han being captured, Luke had his hand chopped off and Vader is his dad. See ya' in a few years. I think the end should stay dark-ish. If you want to make this something forming you could find a way to make it look ominous. I look forward to seeing how you portray it regardless.
