Hey, it looks good!
I kind of see what you mean but it isn’t really a big deal imo.
Do you think Leia and Rey’s sabers being the same color will be enough to imply she is using her crystal? I wonder if you gave their sabers the same ignition sound would help hammer it home. But maybe it isn’t necessary.
Anyway, cool to see this idea come to fruition. Even beyond giving Leia’s saber a function in the story during the resolution of the film, you could argue that purple symbolizes a balance between red and blue, the dark side and the light. Too bad an interesting idea like that is never really expressed in dialogue.
