So I was watching the Warlock-island video and when the camera panned around the green circle with the placeholder human, something struck me as odd. The human had thinner arms, wrists and it's posture was much less He-man and more human... now this could be a conceptual design and I know how designers (I'm one of em) sneak little conceptual models into certain things as placeholders.
Could this be it?
