Confinement + Better than most would think
It's a good animation, regardless of what others say - And I think that needed to be clarified.
The only time I disliked the animation and art style was when he was sailing upward through the air with his 'legs bent', which didn't work - But that's not the point. The reason I wouldn't give it a full ten was because as some people said in previous comments, you could've elaborated on the metaphorbut I believe it was deliberatly short - Still, that's what would've made it better for me.
I believe for such a short piece of animation you made your point validly and created the illusion of freedom sufficiently - I also feel the artistic feel and music did complement each other maybe it wasn't true to the meaning of the animation; but they worked nonetheless.
Good Job and I hope there's more of these somewhere
