Ultra-lifelike 4K film-like underwater photograph of the same uploaded person (face identity preserved 100%, exact facial structure, skin texture, and proportions maintained, no stylization or alteration) suspended horizontally with face oriented upward toward the water surface, as if gently drifting or in a drowning-like posture, body fully relaxed and naturally buoyant. Head slightly tilted back, chest open, arms loose and slightly away from the body, legs trailing naturally—no stiffness, fully aligned with real underwater physics. Camera composed above the main subject looking down at a slight angle, capturing the face turned upward toward the light while maintaining clear horizontal body alignment. The main subject wears an unbuttoned white shirt, flowing softly with water currents, fabric drifting naturally. Strong sunlight penetrates from the surface above, falling directly onto the face and upper body, creating volumetric god rays and lifelike caustic light patterns across the face, eyes, and shirt. Illumination is gentle, refracted, and physically accurate. Face is clearly visible and crisp, angled upward toward the light, with a calm, slightly vacant, relaxed expression (not film-like). Eyes are aquamarine, reflecting refracted sunlight naturally, creating a delicate mesmerizing effect without artificial glow. Below the main subject, a visible coral reef adds depth and orientation, with natural reds, oranges, and purples. Surrounding environment includes a few small schools of tropical fish swimming organically, one or two large sea turtles at a distance moving slowly, and delicate underwater details like suspended particles, micro-bubbles, and gentle marine haze. Keep all aquatic life naturally spaced and not overcrowded. Color grading is film-like with teal-blue underwater tones and warm sunlight highlights, lifelike depth falloff and color absorption. Shot on a full-frame camera, 50mm lens equivalent, ultra-crisp focus on face, moderate depth of field, HDR, global illumination, ray-traced illumination look. Negative constraints: no portrait image-oriented/upright pose, no downward-facing orientation, no stiff body, no face distortion, no identity change, no over-smoothing, no AI artifacts, no exaggerated fantasy illumination, no overcrowded marine life, no warped facial features from water distortion
