I’ve sorta done a 180 on the whole Mustafar establishing shot debate, I’d sorta prefer not to leave reused footage from Rogue One in V2 of TROS:A, so I personally see Biomes as the best option for a shot of the castle. Aside from the glaring issue of those clearly being Imperial TIEs, I reckon the greatest advantage of using that static shot is how much more simple it would be to add some trees in there on the horizon to make it all the more seamless when it plays back to back with the theatrical shots.
