Wow, I thought that cartoon was wonderful! It was mostly because it's just so awesome to see such an amazing twist ending! I'm glad that the animation is so good too. The music is fantastic. You just truly know how to set mood. You really did bring a powerful message.
It's about how we all need to value how important we are. That idea should never die. Even the title is strong. Was the grey guy supposed to be a robot? It would have been more interesting if he was.
