Like many others, I found this animation to be deeply touching. I like how you visualized the hare's emotional state - how the grief and anger literally came over him. I found the combination of his visualized emotional state and his facial expressions to be very effective.
The music was well chosen and synced to the story perfectly. The tone of the animation reminds me of childhood and of classic cartoons many of us grew up with, which is endearing in itself. The animation touches upon my own grief over many things. Well done.
