I am not much of a supers person, but, at a skim, this looks awesome, detailed, comprehensive, and thus "alive." Clearly the result of a ton of hard work and passion. The layout and graphic design could probably use a few polish passes, but it's already 90% there, and I wouldn't complain if this was "shipped" more or less as is. I think the text blocks could use a bit more breathing room, and some of the maps could be made a bit more cohesive in terms of color and line (I love the "highway map" towards the end, more or less as is). I might have made a few different font choices, but that's a very subjective matter.
Anyways, as I said, it's looking great. I hope you keep up the momentum and continue in the same vein all the way to the finish line!
