Never heard this story before, but it's very touching and I like the "moving picture" art you used for your movie.
However, if a voice actor would tell this story in calm words, this would surely help to create a real gentle tune here. Nonetheless, a nice gem I liked to watch, deserves more views for sure.
I love a happy ending... What? The prince died? I know, that's what I'm talking about! Pretty good artwork overall, could have had a little more motion.
