Oh, I love these! The detail in them is incredible, and the effects to sort of scorch/age the paper are just brilliant. I can definitely visualize the use of them in a story, especially the more regional battle maps.
From how you've shared them, it's sort of like zooming in on the specific space. Definitely a technique I plan to do in my own story should I get the motivation/opportunity. Well done. I would shrink the arrows, though. They look sort of cartoony on top of the map texture you've utilized, but I would still use the theme of your last map. The black and gray arrows, just more narrow, would remind me a lot of WWII battle maps that I've seen.
