Could very well be a reference! And I love his design; in fact, I love every character's design that I've seen.
Concern: Looking at all the footage, objects seem to appear out of thin air sometimes... I'm not sure why. Draw distance? It makes the game look unpolished. I hope Playtonic can fix that before release, otherwise it ruins the immersion -- for me, anyway. One of the interviews also mentioned clipping through the floor a few times...
And as I mentioned in my post above, there is room for some extra animations and effects. As many people have said, the red/white rings disappearing so suddenly is quite odd -- maybe it should release a burst of glitter, light or something.
