I have to say, this video was very relaxing for the most part. You really knew how to merge the music with the animation. The ending was also very unsettling, which is what I think you were going for, however, it was a bit hard to understand the story of the video. For the actual animation itself, try doing full animation. I mean, try to key out the poses, and try to fully animate them. It would definitely benefit the video, and make it seem more "alive." Also, to eliminate those black bars at the side of the video, make the stage size for your animation 800 x 450 pixels. You definitely have a spark, so try to keep going! You have great directing chops!
