Very well-drawn.
I like your outline width-variety and the style of your outlines.
I would love to see a 1-pass shading on your coloration. That would give the animation a much greater depth.
Music is well placed and really helps to transfer the mood and feelings to the viewer.
The story, in fact, is not the best but well told, mostly with screenplay.
All over I'll give you a 4,5/5
Keep up the good work! Happy to see more of you in the future.
