That transition works really well. I have a tiny nitpick with the music at 3:10 as the Razor Crest jumps into hyperspace. The timing sounds slightly off flowing into the credits. I can’t quite place it but it seems like the Mando music gets cut off a second too soon (or maybe needs to be extended a tiny bit).
The Mando music fades out to nothing underneath the blast of the end credits. Is it the Timing of the hyperspace noise that’s the problem? Pushing the end credits music any later creates a step.
