What you will get

A wide concept-art view of a sunken city with your architecture covered in coral, fish weaving between buildings, turquoise light shafts from above and drifting bubbles.

Why it works

Underwater concept art depends on light and depth, so the prompt asks for sunlight shafts, bubbles and a wide establishing view. Coral on the architecture tells the story of time passing. Naming the architecture style gives the city a culture, so it feels like a real place that was lost.

Common mistake

The scale is unclear.

Fix: Add a tiny diver near a doorway, as the tip says. One small figure makes the temples feel huge.

Also watch for

Everything is the same blue. Ask for warm coral colours on the buildings and the water fading to deep blue in the distance.
The buildings look new. Ask for cracked columns, toppled statues and coral growing over carvings to show age.

Try a variation: lit at night

Ask for the city at night with glowing jellyfish and bioluminescent coral lighting the streets.
