Very nice
I really liked the references to the previous installment, even though it was not a direct sequel. The animation was good and it was nice how it ended with everyone crying to wrap things up.
I do have some bad news for you. There's a comic strip called "Pearls Before Swine" that had a comic strip ending in a punchline where a character was talking to letters of the alphabet. The letter "x" was very mean, and it was hard to talk to his "x". I am sorry someone else beat you to this joke first.
