The audio is inconsistent, between crappy and alright. It is very distracting.
Second, I think you need to work on your script. It's a little trite, and very pretentious. Frankly, you're not covering any new ground here. This isn't challenging, and it doesn't make me thoughtful. It is actually only a shallow facsimile of depth.
If you want to fix it, get rid of the editorializing. Instead of saying "a restless woman going home to her kids blahblahblah," actually, you know, describe things and show us with your animation. Like, "The woman next to me fiddles with the corner of her bag-- she seems restless, tired, anxious to get home. I wonder if she has children waiting for her blahblahblah."
Also, your description of the man makes me grind my teeth, so definitely change that one.
