It was beautiful. Really. I grew up with this animation, watching the first when I was in the third year of my highschool, and now on the fifth of college, if I remember well.
As much as it pains me saying so, now I've watched the ending. One I Loved. This is it. It needs no further animations, but if you do want to do them... provide them with an ending, as good as this one, or better.
Every good story has an ending. I've seen too many artists afraid to put the word "the end" on a project, and then going to other projects without ending the first when they get tired of the first.
Be Brave.
