Vintage 90s Grunge Boy Portrait | Oversized Lime Green Jersey Aesthetic

Create an ultra-realistic vintage 1990s-inspired portrait of a young man in a casual, slightly messy bedroom with an authentic grunge aesthetic. Use the uploaded reference photo as the only identity reference, preserving the exact facial features, natural skin tone, hairstyle, and overall appearance. The subject is wearing an oversized lime-green vintage sports jersey with bold dark-green number “88” lettering on the front, contrasting double stripes on the sleeves, and relaxed dark charcoal-grey baggy jeans. His dark hair is naturally tousled and slightly messy. He stands casually with one hand resting on top of his head, fingers running through his hair, while his other hand is tucked into his jeans pocket. He looks directly at the camera with a calm, slightly serious expression. The background features an off-white bedroom wall covered with vintage music posters, including Nirvana posters, handwritten notes, and paper clippings attached with yellowed masking tape. A cluttered bed with scattered clothes, pillows, and tangled cables adds an authentic lived-in atmosphere. A wooden shelving unit is visible on the right side. Use direct on-camera flash photography, slightly harsh shadows, natural skin texture, subtle film grain, muted vintage colors, realistic fabric details, and an imperfect early-2000s point-and-shoot camera aesthetic. Maintain natural body proportions, authentic clothing folds, and realistic indoor lighting. Frame the subject from head to upper thighs in a vertical 4:5 composition. The final image should look like a genuine candid photograph from the late 1990s or early 2000s, not an artificial or overly polished AI image. Preserve the reference person's identity exactly. No skin smoothing, no facial distortion, no extra fingers, no watermark, and no added text. 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.
