It's absolutely beautiful!
What a job! So many details, so much precision!

Personally I am really reassured by the disappearance of these blue lines and I applaud the structure of the frame: the whole atmosphere is given by this so complex city and this majestic statue. You really rendered the steam punk style extremely well!
The challenge now is to make the map stand out in as talented a way as you drew the border, so that the frame doesn't eclipse the center! I'm confident that you'll succeed!
