The city name - "Dragons mouth" - should be "Dragon's mouth" to be grammatically correct. That said, language warps over time and especially names tend to change towards the easier-to-spell or easier-to-say variety. "Dragons mouth" or even "Dragonsmouth" could be just as correct. I just think it should be a conscious choice rather than a blunder
The map is awesome (which goes without saying for your maps in general, it seems). You originally said the city would be domed and partially under an overhanging rock. Is the rock anywhere to be seen yet? I can't find any signs of it.
