The puppet show turned out amazing! I love the tusks and claws on the walker, and I love how the childen looking back and forth makes the interaction of the puppets feel seamless. I’m curious to see how it could be extended but I think it works perfectly fine as is.
It’s a subtle (and wonderful) nod to TLJ but we should be careful not to put too much emphasis on it, since it could end up taking emphasis away from the children, which are an important part of the scene. Also I think the laughs of the children should be a bit louder to match the volume of the alien speech, that would help blend the two elements together.
