Candid Field Portrait of a Young Woman

A photorealistic vertical portrait of the young woman from the reference images, preserving her exact facial identity, long sleek straight brunette hair parted in the middle, and natural, cheerful smile. She is sitting casually barefoot on a lush green grassy field, seated with bent knees angled to the side. She wears a relaxed, loose-fitting heather grey crewneck sweatshirt featuring faded blue collegiate lettering across the chest, paired with wide-leg, loose-fit medium-wash blue denim jeans that drape naturally with room throughout the legs. One hand rests gently by the side of her head while her other arm rests across her knees. The background features soft, out-of-focus springtime green trees under soft, diffused natural daylight, with gentle foreground blades of grass creating a shallow depth of field. Maintain the exact vertical 3:4 aspect ratio, subject scale, natural skin texture, and candid outdoor photographic composition of the references. 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.
