I am more certain of Rey having a slight glow (kinda force ghost but not as strong) over the shield. Been thinking about this in the back of my mind all day and I think that will be the best outcome to keep it subtle and really help the idea of the force ghosts “empowering her.”
Also, if anyone else is able to since I am more than useless when it comes to this kind of stuff … Changing the lighting redirect to either purple … or even yellow maybe to match Rey’s lightsaber at the end … would be nice too. It needs to be more than just a “simple” redirect … Either yellow or purple lighting being redirected would really seal it all up.
