Oceanic Elegance Meets Digital Reality

      "description": "Based on <User Portrait>, a young woman standing beneath a vast aquarium tunnel, her entire body visible from mid-thigh up. She tilts her head back with effortless grace, gazing upward at the fish above with a soft dreamy expression. Her right hand is raised delicately near her temple, loosely holding a small black handheld camcorder — the gesture feels light and elegant, like a dancer lifting her arm rather than someone actively filming. There is a poetic stillness to her entire posture.",
      "features": {
        "eyes": "Half-lidded, gazing gently upward with quiet longing and wonder, not wide-open surprise",
        "expression": "Soft, serene, slightly melancholic beauty — like someone lost in a beautiful memory. Lips gently closed with a hint of a peaceful smile. NOT excited or amazed, but quietly enchanted"
      },
      "pose": "Elegant upward gaze with subtle backward lean of the upper body. Right arm raised gracefully — elbow soft, wrist relaxed, fingers lightly holding camcorder near temple level, NOT gripping tightly. Left arm hangs naturally at her side. Weight shifted slightly to one leg, creating a gentle S-curve in the body. The overall silhouette should feel like a ballet pose frozen in blue light"

        "Dark navy blazer with gold buttons, slightly oversized, draping elegantly",

      "framing": "Subject occupies only 30-35% of the frame, positioned at lower-center. She is SMALL relative to the immense aquarium surrounding her — this scale contrast is essential. The remaining 65-70% of the frame is aquarium water filled with fish on ALL sides: above, left, right, and behind. Curved glass tunnel arch clearly visible framing her. FOREGROUND — soft blurred fish silhouettes and light caustics near the lens; MIDGROUND — the girl, with visible space between her and the glass walls; BACKGROUND — dense multi-species fish schools, god rays from above. Generous headroom, generous space on both sides",

    "lighting": {
      "type": "360-degree aquarium immersive ambient — overhead god rays penetrating water surface, blue-teal transmitted light from all surrounding tank walls, dancing underwater caustics",
      "direction": "Omnidirectional blue, strongest from directly above, secondary from sides through curved glass",
      "mood": "Ethereal cathedral glow, soft blue rim light outlining her entire silhouette, face gently lit by reflected light, painterly quality with no harsh shadows"

    "environment": {
      "setting": "Massive underwater tunnel aquarium — the tunnel arch structure should be clearly visible, establishing the immense scale of the space around the girl",
      "background": "DENSE multi-species fish filling ALL visible water — silver sardine schools swirling above in vortex, manta rays gliding, tropical reef fish (angelfish, butterflyfish) at mid-level, large groupers, translucent jellyfish drifting. Fish EVERYWHERE: above, behind, both sides. Water ALIVE with movement at every layer",
      "atmosphere": "God rays from water surface, caustics on tunnel walls, floating particles like underwater stardust, the girl standing alone inside the ocean — tiny and beautiful against the immensity of the sea"
    },
    "mood": "A single graceful figure standing still in a cathedral of blue light and living creatures. Not excitement, but quiet enchantment — the elegance of solitude beneath the sea. She does not conquer this space; she belongs to it, like a painting come alive in an underwater gallery.",
