Brilliant
Crisp, clean and beautiful. This summarizes your animation perfectly.
You have completely understood what most amateur animations lack the most - tempo. With fast cuts and dynamic camera movement this animation conveys a sense of live action. Your graphics are great and the detail of the characters breaks nicely from the more suggestive backgrounds. You do use a lot of tweens and there is not that much actual animation, but you seem to know exactly when to put that little extra effort to lift your animation to a whole new level.
The song fits the animation perfectly (or the other way around) and I think that sound effects would have ruined it, so good work on that.
I enjoyed this very much and if there is anything to wish for it would be that you turned this into something with a story, so that we get to see more of this world of yours.
Great submission!
