Need help with a tattoo concept

So I have a large rat on my left arm, elbow to shoulder, and i want to turn it into a half sleeve with a burning city in the background. Grey scale with flame highlights.

But I can't decide what city or what type of buildings. My first thought was generic modern sky scrapers. Now I'm leaning maybe towards symbols of empires throughout the world and history. Like a japanese castle, an Aztec temple , the Parthenon and of course the statue of liberty, not sure what else. Any suggestions for specific buildings or imperial styles?
