First, I want to thank the editor for sharing this. I saw the first work print movie, and it was very well done. I never watched the show, which makes this my first time going through this. The editor really did a very nice job with this.
While watching this, I never felt like anything was missing. The narrative was clear and the pacing of the movie felt natural - not too slow and not too fast. I never felt that I was watching an unnecessary side quest irrelevant to the main plot threads. Everything included was essential for a cohesive narrative. Even the intermission point was relatively well placed to give the audience a nice break point if you were looking to break up watching this.
It is hard for me to say if any changes are really necessary. I know the show itself was well-reviewed. There likely is not much to cut anyway. I probably should watch the show itself to give better feedback for potential changes.
One thing I can suggest is to make your own custom fan edit introduction. Something memorable, and dare I say biblical. It could be anything you imagine. An example is posted in the first few seconds in the video below.

If anybody comes across this, I would strongly recommend watching this edit. I think this edit could draw more interest if posted in other forums such as the fan edits reddit forum that is the most popular for spreading fan edits.
