Concept for a personal project 'aRevolution'.
Richer and more influential citizens, who used their connections well or were smart enough to use the economic growth since the aliens' arrival, live in floating mini-islands, hoovering over the Atol. Each island has self-sustaining energy source, temperature controlling and air purification systems. Small docking stations with syntetic fuel generators and/or ion chargers take care of the vehicles.
Depending on personal preferences (and capacity of the wallet), floating islands can also have luxurious pools, gravi-chambers and other attractions. They can also branch out and to create additional mini-islands but they need to be connected to the main one and its power source.
That looks so amazing and photorealistic! You deserve way more loves than that. Even the stories behind them are art!
