I really did enjoy this animation of yours, but I'm probably a little biased since I love silhouette animations. It's quick, it's to the point and I thought the art style was really nice. The little things were what I probably liked the most as I found myself constantly being drawn to the little edges in the backgrounds, such as the twisting blades of grass, or watching the mechanical parts spin, the clock Abraham gave to his wife was especially nice since everything moved so fluidly within it. The music had a haunting quality to it and I thought it fit well with the art style.
That being said there were only two issues I had with this animation. The first is the obvious lack of a replay button, though that itself isn't that big of a deal, just something to remember next time. The second issue is that the music would cut out randomly sometimes when I was watching the video and I'd have to start it over again. I'm not sure what caused this but it's something that you should look into, plus there's that popping sound every now and then.
Perhaps a little more depth might be in order but it's the subtle things that shine the brightest. Good job.
