Wow, this looks great! The actual animation was slick (very reminiscent of works like HISHE) and the attention to detail really elevates the whole sequence (Tony's t-shirt, the Boba Fett helmet). The only thing I'd say is that their faces looked quite bland. I understand the art style you're going for, but you might want to try shading a little bit just to add a bit of depth.
