Hey MrStimpson, thanks for dropping them here! I honestly just think they're pretty great for having just started.
In the second one I can see the text and borders being darkened though, especially since it overpowers the dark map (even without the map, pure white on black is kinda hard on the eyes!). And in that one those doors (?) are an unusual glyph choice. At best maybe use those for windows, and try something else for doors.
I love the atmosphere and flow/layout of the last one!
