I thought of two things just now:
1. I haven't said how much I like this style, I think. The light blue and the red, the subtle paper texture, the borders and cartouches, everything fits together in a very beautiful and unexpected way. It feels sci-fi, fantasy and historical at the same time, without any clichés. Which, I realized as I typed it, is quite the accomplishment.
2. Since they are all going to be in an atlas and show the same time period, maybe the cartouches don't have to say "A map of" and "In the age of the Reaffirmation Wars"? Unless there's a point to the repetition, it feels mostly like… repetition
