Short and sweet!
I did have to watch it three times to fully absorb the entire message though. I feel the information in the video is slightly scattered because of the text, the characters, and the flowers being so separate. I felt like I had to really pay attention to the lyrics, thus reading the subtitles, while trying to not miss anything of the animation (which also is the star of the show of course, I don't wanna miss the great work you did). This made me entirely miss the flower the first time I watched the animation.
So to visually push the importance of the flower I think would have been favorable. Perhaps a scene with the flower completely isolated fully on screen could have helped communicating to the viewer to keep an eye on it through out the video. And/or keeping it a bit more centered in view as it is quite far down on screen.
Either way, this was a very nice animation with a quick and simple message and I enjoyed it. Great job on it and I hope my review was perceived as helpful!
