I like the concept here, though it feels like it needs to give a bit more in each location for a GM to latch onto when prepping. Something like an unusual landmark, strange inhabitant, or an atmospheric description to get the inspiration going.
I'd also second the comments on the layout, like expanding the black background areas on page 2 to give the text more space to breathe. I understand it can be hard to keep all that in mind when you're working on a tight deadline though, and I'm impressed you put this together in just 3 days.
