Beautifl map, Citabria. I really like the way map doesn't abandon a realistic, natural appearance for the sake of game playability.
Couple of things - there is a terrific natural harbor in 2,9; it looks like it would be a prime spot for a port in RL. Also, the shoreline in 16,14 appears to be a perfectly straight line along the meridian. Maybe it's just the map scale but it looks unusual.
Thanks for all your work on this terrain ! I can't wait to try it out!
