Totally understand, and thanks for letting us know. There is no rush! Sorry you have gotten this far and realized you’ll need to go back and redo a lot, but if you’re gonna do the work, might as well make it look as good as possible.
Also, I’m happy to hear you’ve grown fond of the movie as you have been working on it. I’ve had a similar experience myself, the more I go back and watch bits and pieces of it. I’ll go in wanting to just watch one scene, but then I have trouble keeping myself from watching the whole thing!
