Wow, this looks awesome! I love the just-bold-enough colors and the overall style. I can't help with the technical side here (though I agree that it would be better if the fields didn't fade out), but I'll offer a couple of thoughts on the aesthetics. Your three main fonts don't match, in my eyes; one retro-modern sans-serif, one fantasy Roman style (Charlemagne, I think?), and one quite flashy sci-fi. I'd suggest changing the two latter for something cleaner, similar to the city font. I also think the title and border is a little over-worked – when the map is this packed with small detail, you don't want anything distracting from it
