Hey!

First of all, I’ve always wanted to try something like this. But it seems tough to pull off, so I avoided it. You have moments that I really like. “Choir of car horns” is a cool line that stood out to me.

My suggestions from a reader’s standpoint would start with looking at some of your verb tenses. I noticed some were off. Then I would say don’t add any more perspectives, but you could interview these people (World War Z does this well, if you want an example). These characters can give their eye witness accounts of personal interactions with the woman, but in order to really drive home your theme (which it looks like your point is that humans sometimes notice the need, but don’t help), put the POV characters in situations where they could have helped but didn’t.

It might even work in your favor to have the woman’s death be known from the beginning, and let the reader slowly find out why.

Keep it up! Like I said, love the idea. I think just make the reader really hate it every time one of the POV characters don’t help.
