COMPOSITION (FIXED): One large main photo in the center, two smaller rectangular photo frames placed diagonally on the right side, no extra frames, no layout changes. POSE (FIXED): The subject is seated on a simple round studio stool, feet flat on the floor, elbows resting on thighs, hands relaxed and visible, upper body slightly leaning forward, head straight, eyes looking directly into the camera, facial expression neutral, calm, aesthetic, no smile. OUTFIT (FIXED): Oversized plain black t-shirt, loose-fit black pants, clean white oversized sneakers, no patterns, no logos, no color changes. BACKGROUND (FIXED): Solid light gray studio cyclorama background, even lighting, no gradients, no textures. 3D ELEMENTS (FIXED): One 3D Instagram logo floating on the left side of the subject at chest height, two small 3D heart icons near the bottom right, all icons must appear as physical 3D props with realistic shadows, no additional icons. LIGHTING (FIXED): Soft studio key light from front-left, fill light from front-right, subtle shadow on floor, no dramatic lighting. CAMERA (FIXED): Full-frame DSLR look, 50mm lens, f/2.2 aperture, ISO 100, eye-level camera angle, ultra-realistic skin texture, natural colors, real studio photography look.
