I'll third Ravs, your description sounds just like Bladerunner. With that many people I would think that there would be numerous levels of maglevs, the problem is how to represent them and do they really work? I can't help but get the traffic scene from the 5th element out of my head...floating cars everywhere. As far as what you have here, it is very clean and clear and professional looking and that's a good thing, now ya gotta rough it up
