Ok, just a couple of things.
I don’t know if I can add the Death Star surface, simply because I’d have to add it to every window, and with the moving camera (especially during the fight) I’m pretty sure I can’t motion track a still image.
Also, the planet outside would have been only in that single scene (Vader and Palpy talking), just to give the idea that the Death Star is moving between scenes.
So… I’ll either leave it as the original or keep the planet only in this scene…
