I think y’all are right, and thanks for the feedback. In the abstract this film needs more establishing shots but that specific moment isn’t ripe for wedging one in.
The Mustafar shot really would just need some simple color correction and some TIEs. Agreed, some trees or the hint of some would seal it. (And to darken the ‘hearth’ inside the castle. Or maybe not since we see the lava flowing out from the front.)
