Digital Octopus in Ancient Greece Underwater Ruins

Ultra-detailed digital painting of a colossal octopus swimming among ancient Greek underwater ruins. A sunlit chamber of a Doric temple lies on the sea floor, its fluted columns encrusted with coral and seaweed, marble statues half-buried, and mosaic fragments with meander patterns. The octopus displays iridescent blue-purple skin with glistening suction cups, tentacles curling around columns and carved reliefs of olive wreaths. Light filters from above in golden beams, creating dramatic caustics and shimmering reflections on wet marble. In the background, a sunken trireme, fish, and bubbles drift through the blue depths. Style: digital art, highly detailed, painterly textures, vivid color palette, cinematic lighting, 16:9 aspect.
