Nev, it’s looking really fantastic! Two things stand out to me though:

Looking at the clouds in the new shot, compared to the clouds in Ascendant, I think the new shot needs to be a bit more pinky/orangy? I feel like it’s not a 100% match yet.
I still personally would opt to keep the original forest flyover shot in the sequence. Like I’ve said before, it’s the shot that feels most connected to the action on the ground, so it’s the shot that truly feels like the bridge into the action. Especially if there aren’t going to be any visible TIEs in the Castle shot, I think there needs to be a visual connection between the ships flying down to the planet, and the ships reaching the forest. (Before we actually land in the forest.)

Also, was someone working on darkening the ground in the theatrical Mustafar footage? Doing a side-by-side of Nev’s new shot and the V1 footage, the difference in color tone is…apparent.
