I like the Sith eyes as a way to make “Evil Rey” her own distinctive character, making it clear when she shows up on the Death Star ruins that it’s the same Rey we saw sitting on the throne in the vision, she’s meant to be the embodiment of Rey’s ultimate dark fate, but that wasn’t really clear on theatrical. which is why I’m not a fan of using the shot from Starlight on the Vision with her Sith eyes on SKB, it takes away from the impact of seeing Evil Rey on the throne, though that’s also because I prefer Hal’s Restructured episode VII, so in my version of the trilogy it just comes off as an odd choice to have a single shot from a previous movie edited to make Rey look extra evil.
