Vintage portrait of a young woman.

Create a realistic vintage portrait of a young woman sitting cross-legged on a bookstore floor, surrounded by stacks of books. She wears a white turtleneck, denim overalls, round black glasses, and long straight dark hair. She reads an open book with a calm expression. Warm moody lighting, muted colors, nostalgic film grain, candid photography, authentic bookstore atmosphere, cinematic 90s aesthetic. 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.
