I agree the thematic use of the Sith Spinning Scream is a bit shaky, but in terms of how it would sound in the moment, I really love the idea. It’s worth trying out at least.
I definitely think its worth testing the sound right as he explodes; or slightly after.
Found a way more echoed version in SWBFII,Concept: https://cdn.discordapp.com/attachments/702816288342278207/847721533132898334/Sith_Scream_Final.mp4
I really think this is great.
