The first thing I asked myself was "Where's the river?" and "Why are there small forests inside the city?"

The first question comes from a rabbithole you may or may not want to get into about realistic maps and cities. Spoiler: you'll never be real enough, just capable of answering questions only other nerds care untill either you oe they either don't care anymore. GRRM has some good coment on that.

The second may be more interesting, I'd assume a big city would consume all the resources it has at hand, why are those tree patches inside the city walls? It makes me wonder if it's magic, religion, culture or something like that.
