well it doesn't quite make the cut
The main problem with this animation is the length and also execution of it at the end. When you are making a short animation it is really important that the ending really has a strong execution which wasn't really there. The strong animation points of this video were the backgrounds rather then the characters themselves which would have some conflicting hierarchy. Try to keep these issues in mind and I'm sure the next animation you come up with will be very entertaining so just keep working at it.
