Chân Dung Gia Đình Studio Đối Xứng Thẳng Đứng

Strictly preserve the appearance of all four subjects from the reference photo 1:1—faces, facial features, proportions, age, skin texture, hair length, and hair color, without artificial smoothing or retouching. Black and white studio portrait in a vertical symmetrical composition. Four people aligned strictly in the center in a single vertical column: at the bottom, [the youngest child] looking directly at the camera with a subtle natural smile; directly behind and above, [an older child] with hands resting gently on the crown of the younger child's head, fingers intertwined, soft lively smile; above them, [a woman] with hands resting gently on the crown of the older child's head, fingers intertwined, soft lively smile; at the top, [a man] standing behind the woman, palms resting gently on her head, fingers intertwined, calm and confident expression looking directly at camera. Everyone wears identical [plain black turtlenecks]. Background is [pure solid black] without texture. Soft, sculptural front-high key lighting, moderate contrast, crisp skin details, natural matte finish.
