I liked the video. It was amusing. I didn't mind the lack of an Australian accent - they explained it as Dave having watched Star Wars so much that summer that his accent might have changed to American.
I also watched part of the "making of" video. It was interesting.
Raising Awesome guy, you know that's a model of a Saturn V rocket, that was already around for about a decade by 1978? I wasn't sure when you said you're showing the model half finished. Maybe you knew the actual rocket was already finished, but just meant that Dave hadn't finished building the model yet in the 1970s.
