My original worry with some of the graffiti was that it was going to be too subtle for casual audience members to catch; but I think it would actually work perfectly if we can iron out the rest of the audio for this sequence. More observant viewers would be able to see that Kijimi was inspired by Luke by looking at the graffiti, and that then quietly foreshadows the moment with Poe later where it comes to the forefront; but the point of all of our additions is still made clear for those yuppies who won’t pick up on little clues like that. Kind of an /r/MovieDetails moment.
I agree with this. Kijimi in riot is a great idea, in my opinion; as someone else said in this thread, taking disposable moments and pumping them full of meaning.
