Aqualunar Vision: Astronaut in Deep Sea

Ultra-detailed concept art of an astronaut submerged underwater, drifting through a sunlit abyss. A weathered white-and-orange spacesuit with a reflective helmet visor reveals a coral reef and bioluminescent life in its reflection. Surrounding the suit are swarms of fish and wisps of kelp; bubbles rise toward the surface. Dappled light pierces from above, creating volumetric rays and shimmering caustics on the seabed. In the hazy distance lies a sunken spacecraft and distant ruins, hinting at a forgotten mission. Mood: contemplative, awe-inspired, a fusion of sci-fi and marine fantasy. Style: cinematic digital painting, high-detail concept art, painterly textures, cool blue-green palette with warm amber accents. Composition emphasizes diagonal motion and solitude of the explorer.
