An ornate steampunk owl perched elegantly on a twisting, mechanical tree branch. The owl features an intricate anatomy of interlocking brass gears, polished bronze plumage, and whirring clockwork eyes with glowing cyan crystal lenses. Its wings and chest are decorated with sweeping, fluid Art Nouveau filigree patterns, embellished with brilliant, shimmering gold leaf accents. The mechanical branch curves gracefully across the frame, detailed with micro-etched metallic bark textures and small, unfolding copper leaves. The entire scene is set against a pitch-black, void-like environment, completely devoid of ambient light. High-fidelity 3D digital sculpture, masterfully rendered with Octane Render and Unreal Engine 5. Shot with an 85mm prime lens at f/2.4 aperture, ensuring razor-sharp focus on the intricate details with an ultra-shallow depth of field. Surface textures exhibit high-contrast micro-details, including metallic patina, brushed copper grain, and the distinct reflective irregularities of hammered gold leaf. Illuminated exclusively by an ethereal, vibrant bioluminescent cyan and deep teal glow radiating from within the mechanical torso and the branch's translucent internal veins. The intense bioluminescence creates dramatic chiaroscuro lighting, casting sharp luminous highlights, soft volumetric scattering through a faint mist, and deep, rich obsidian shadows. Color grading features high-contrast tones of brilliant gold, deep copper, and radiant neon-blue against absolute black. --ar 16:9 --v 6.0
