Looks good to me, and I like the proposed sequence of events, too.
Wasn’t something I thought needed addressing myself, but the regrade looks natural and it doesn’t hurt anything, so I don’t see why not.
Not sure about the Apocalypse TIE shot though, seems like an awkward and unnecessary insert to me as you currently have it. But then again I never had much of a problem with that shot’s placement in the film as it stands.
