Apart from a scene or two, for example the scene with the red horned guy getting a glass thrown at his face, and the tone of voice of some of the speakers at times, I thoroughly enjoyed that piece. The scene seemed to break the flow of conversation between the two stormtroopers. Personally, I'd just have replaced the example scene with a loud audible shout of agony following the glass throw. I would also have changed the tone of voice on Kyle at times, maybe added some stammering for realism, and would have cut out the helmet voice masking just a tad, it almost sounded static-y. Finally I'd make the cousin's voice slightly... different. Mocking, older, maybe?
Apart from that, it's been a while since I've seen a funny simple conversation video done right. And as an aside, maybe a clip of the death star exploding at the end would have been a nice touch. Seeing as they just relocated onboard.
