That’s good (the briefing scene)! I see some small issues. It needs BB-8 foley, “any word from the republic” sounds a little odd around the “the” (perhaps someone could record a new line?) and the shot of Leia saying “no” could perhaps be better (maybe slightly animate the mouth to an O shape) but otherwise it seems like a good way to do it.
The deleted scene works great! Needs some work in the audio department (and visual, of course) but I like what you’ve done.
