A sudden thought upon rewatching that “I am a Jedi” clip: could we get a noticeably audible Skywalker Saber ignition sound in there?
When she catches Anakin’s/Luke’s/Rey’s saber behind her back, it’s turned off, and then when things go silent and she says “… am a Jedi,” she pulls it up already turned on. I think it would be nice if, after she says “I am a Jedi,” right as she pulls up the saber, we hear it loudly ignite off-screen as the sound that breaks the silence of the moment (rather than the growing crackle of the lightning).
It would really solidify her declaration of being a Jedi, and the idea that she’s taking up the Skywalker legacy, if in that moment we clearly hear that iconic, distinctive lightsaber sound, for the final time.
