Personally speaking, I do like the idea of having the Sith Whispers being in this final confrontation as being a last temptation sort of thing (even though it doesn’t really make sense in a 1:1 interpretation since Palp’s is trying to kill her at this point but whatever).
However, I’m really not a fan of the echo voice for Palpatine. It just seems really hokey to me (although you have done excellent work with it, Axlanian!)
EDIT: Here’s a really rough mockup of what I was thinking for this scene using Axlanian’s whispers, Hal’s whispers and SWTOR whispers for the final scene that I posted in here. It kind of got glossed over though. lol
I have two versions of the scene. The one that I’ve preferred this entire time (having Palp’s final line being “You are nothing!”): https://streamable.com/am0y0m
And then there’s the version most of you guys seem to prefer and the one you’ve been all doing your edits with (having Palp’s last line be the “Scavanger girl” line): https://streamable.com/jl01wu
