Vertical studio portrait of a close-knit family stacked in a playful head-pile

Vertical studio portrait of a close-knit family stacked in a playful head-pile: two smiling young boys resting on the shoulders of a woman, who sits atop a young man lying with his arms folded. All four wear matching warm brown ribbed knit sweaters and light trousers, cohesive styling. Soft, even studio lighting with gentle rim highlights, neutral light-gray backdrop, creamy skin tones and natural makeup. Warm, intimate mood, genuine smiles and relaxed expressions, subtle catchlights in eyes. Sharp focus on faces, shallow depth of field (85mm portrait feel, f/2.8), high resolution, fine skin detail with natural retouching, minimal grain. Color palette: warm browns, soft neutrals, muted grays; slight contrast boost and warm toning. Compose centrally with symmetrical balance, full head-to-shoulder framing, visible silver wristwatch and glossy dark manicure as tasteful accessories. Deliver photorealistic, editorial-quality family portrait with soft shadows and lifelike texture. Insert discreet watermark in the lower right corner of the image, vertical text (rotated 90°), written "aipromptlabs.online", Calibri Light font, white color with low opacity (semi-transparent), medium size. Extreme sharpness on the face, fabric texture and typography of the letters. Shot on Canon EOS R5, 50mm f/2.8, studio light.
