Um submarino steampunk ornamentado flutua numa vasta caverna subaquática

A cinematic, highly detailed photograph of an ornate, retro-futuristic steampunk submarine, built with a polished ivory hull and complex polished gold filigree and fittings, as the central focal point. The submarine, inspired by image_3.png, floats in the clear, deep-water of a vast aquatic cavern. In the far deep background, an expansive, multi-tiered underwater city with Art Deco architectural features, identical in structure and glowing windows to the city in image_3.png, is visible, receding into the blue water. The entire scene is bathed in sun shafts filtering from far above and the city’s lights. The immediate foreground below the submarine, transforming the bare ground of image_3.png, is a detailed and intricate coral reef garden, densely populated with anemones, sea sponges, and branching corals in vibrant shades of deep reds, purples, blues, and golds. Schools of diverse tropical reef fish, including a family of Moorish idols and multiple small damsel fish, swim in dynamic patterns around and over the colorful reef. Larger barracuda and other fish form a school around the far-distant city structures. The submarine's hull reflects the water surface patterns and the city lights. All technical elements of the submarine—bubble cockpits, hatches, deck rails—remain from image_3.png. The depth of field is carefully controlled to make the foreground reef in sharp, realistic focus, while the submarine is detailed and the city is softly distinct. The composition is deep and multi-layered.
