Studio portrait woman casual seated double exposure

Cinematic photorealistic full-body studio portrait of the reference woman, preserving exact facial identity, facial structure, proportions, skin tone, hairstyle, and recognizable features. Soft side-angle, 4:5. She sits casually on a light-gray wooden studio floor with visible plank seams and subtle grain, knees drawn up, arms loosely resting across them, gazing slightly upward with a joyful open smile. Outfit: fitted black full-sleeve top, charcoal-gray straight-fit jeans, chunky white-and-gray sneakers. Loose wavy hair with soft volume and subtle side braid. Seamless gray background with a large translucent monochrome close-up of her face softly blended behind her as a double-exposure effect. Soft even studio lighting, premium fashion editorial aesthetic, sharp subject details, natural textures, shallow DOF.
