Impressive voice acting and musical work and my own generosity made me vote this a 5, but really the animation is pretty awful, so good luck passing judgement. I know animation takes ages and ages, but what can you do?
If this doesn't pass, I'd suggest keeping the sounds and audio and completely rejigging the animation. Make it visually exciting - movement should be constant. Like when they are talking in the rain, the raindrops should be moving; when the kid's name has been stolen you could have his face trembling or something. There should be animation in pretty much every frame; still images don't cut it.
The voice acting and atmosphere and music is exceptionally good though,
