A mythical underwater city of pink and stone towers, arched windows and coral-covered buildings fills a round frame, with striped tropical fish drifting through teal water. Towers, turrets and window blocks disguise the finder squares, while the dense wall of masonry, bubbles and reef shapes carries the dark and light modules. Dark stone and deep blue shadows sit against pale turquoise and glowing orange coral, which keeps the pattern distinct across the whole picture. A large pale moon-like disc glows behind the central spire.
