I don't think you are ever "done" with the characters you animated.
When I finished my last scene with Mama Odie for The Princess & the Frog I remember thinking, I am just warming up to her. An idea for a Mama Odie short film kept going through my head.
How much fun that would have been!
Animating Lilo was very special to me, too , so recently I imagined this little situation which is not in the movie. I used color pencil and watercolor.
