This is my recent project to build a sky (floating) city of steampunk tech. style w/ fully details & lighting inside.
You could enter the city by using balloon (lift) on the ground.
Once you up to the sky city, there are 5 main parts in the city:
- Airships / balloons dock
- Fountain central plaza
- Market w/ shops and temple
- Inns for resting place
- Palace w/ power of the sky city
Besides, there is already a merchant airship parking in the dock to trade with people!
Of course, the palace is fully defended with gates & walls, and a military force of huge battle airship is ready for guarding the city, just next to the royal private dock of the palace!
