I am thinking about adding some tremolo effect to Tarkin's 'This had better work!' line, while at the same time amping up Vader's breathing. Tarkin's tone is now weaker and sort of gives the feeling Tarking is just actually beeing a bit afraid about this plan working out, without '...or else...' feeling at the end.
I'll try to play around with it a bit...if doesn't work out, I'll just leave it in or actually just cut the whole scene. We already have clues that the empire is tracking the MF, as Lea mentions it to Han.
I have tried cutting the whole line, but the scene then ends kind of abruptly you can feel something was cut, so this doesn't look promising.
