Lone Wolf Fists: How do I map this setting, brah?

Working on the map right now. I did a terrible freehand sketch, then a terrible MSPaint sketch, so I settled on doing it in hexographer

Yeah look at that ruined, broken world. It kinda looks like it's on fire. Go Hexographer!

I've been struck with the need to add a new size category to the maps. Right now its:

Largest: Entire Map. All the linked-together Regions

Middle: Regions. City/country sized areas with content keyed to them

Smallest: Battlefields. Apartment-to-football-field sized areas where characters fight

In this set up, Regions are composed of Battlefields. That means that countries are diced up into rough neighborhood-sized chunks; that's a ton of Battlefields.

I'm thinking of adding a "Point of Interest" tier, big enough to contain several Battlefields but small enough that several of them can fit within a Region. 

That will allow GMs to make a given Region come alive with multiple, discrete areas of content. Somewhat similar to the map>hex>dungeon>room content of D&D (if this concept is totally alien to you, I humbly recommend you learn of it the way I did and read these fantastic articles on the illustrious Alexandrian site)

Note: I'm not certain of the legality of using this exact map in a product I sell. I'm also somewhat hesitant about using hexes, since they're largely maligned by modern gamers. So this is just a little rough visual draft to help me create and key some content, not a final map by any means.
