Nah, the LUTs already in use are better, if I remember right.
Here’s two clips. The finished puppet show and conference room (complete with “Captain Hux”).
If you’re after feedback on the stormtrooper lines, they’re a little loud and not very integrated into the scene. A mild touch of hallway or plate reverb and a bit lower in the mix and they’ll be about perfect. Just my $0.02𝇍!
