I have only gotten to the Falcon escape, but I do have some thoughts.

I think Jakku regrade was a massive success. I genuinely love this look for Jakku. Some might find it too bland, but that feeling will make seeing the green of Takodana much more cathartic, imo.

I do think the BB-8 night shots are rather quick as well, but I get why it cuts to him at that point. I did have another thought though. Since we moved Ren’s line “I’ll leave that to you” Maybe in its place you could put something like, “Kill the pilot.” Poe gave them the information they need, he is no longer useful. Maybe when Finn walks in, he could say, “The Captain wants the prisoner.” So the audience might think he is about to be executed, maybe by Captain Phasma on Hux’s orders, then it turns out to be Finn trying to escape. Maybe that could help the transition between those two scenes?

I’ll have to comment on your other questions as I get farther into the edit.
