That chapter was great! To be honest, I’m not a fan of sad, or depressing endings, so If that was your ending, it’s not MY type of book, but that doesn’t make it bad. I really loved the depth you gave, and your choices in structure were wonderful, I know that is just the intro, but I would make the following chapters longer. The concepts of color/shade(e.g. black, white, grey) and perspectives(the section mentioning bystanders and understanding) are both things that could be great to carry on through the story, to help keep that sense of depth and symbolism.
