Pieced together in more ways than one
This ranks up there with my personal best. The whole thing was like a puzzle., a puzzle that not only involved the story line, but the concept, music, tone, and mood. The music really fit the the overall mood presented through the use of symbolism and making the entire submission black and white (save the mask details).
Though, like you said, animation isn't the best, every other detail used here made up for that entirely. You truly spoke to the hearts and souls of the viewers with this submission.
