This change looks good, and I like your reasoning behind it. I always felt like BB-8 needed to be part of that scene, and this edit pulls it off well.
Visually, I didn’t like the shot of Chewie, Poe, and rando Resistance member that interrupts BB-8 rolling forward. It just felt choppy or too quick or something. Would the shot of Rey looking at the map be a better fit here? Or would that be too awkward after having seen her in the Luke/dream sequence?
