This is one of the most creative fan edits I have seen of the sequel trilogy, of course why not put Snoke on Exegol? Great idea, as for the sibling dynamic, there isn’t enough here to feed into that idea. Not your fault just a lack of source accessibility, If you could just keep Rey’s name to Rey then that would fix it!! I was surprised by how much you cut out of episode 8 and 9, but the edit works without that cut footage!
Solid edit, 7/10
