Hallo und willkommen zurück randigpanzrall! I really like the layout of the city, it looks very convincing to me. The only nitpick would be about the mentioned age of the city. You wrote it's only about thirty years old, but with its rather huge size it looks like it is grown over a longer period of time. Also the "Oldtown" seems a little strange in that context. Besides that it's a very fine piece already. Keep up the great work, i'm looking forward to see it coming together!
Cheers,
Martin
