Olive Backdrop Studio Fashion

Create a studio fashion portrait. Subject: a woman with long straight black hair falling forward over one shoulder past her waist, seated on a dark wooden stool with a rung near the base. Warm deep skin, natural makeup with softly defined brows and a glossy nude lip. She wears a loose oversized beige linen shirt with a soft collar and long sleeves, the top buttons open, tucked into high-waisted cream wide-leg trousers. Barefoot. Action: perched on the stool with her body angled to her right and her torso upright. Her left foot rests on the stool's lower rung with the knee raised high in front of her, her right leg extends down with the bare foot flat on the floor. Both hands rest loosely together on the raised knee, fingers relaxed. Head turned back toward the camera, chin level, calm unsmiling gaze into the lens. Setting: a plain seamless olive-green studio backdrop, untextured, with a soft diffuse shadow falling behind her, the floor merging into the backdrop. Visual style: photoreal studio fashion photography, warm muted olive and cream palette, fine grain. Composition: full-length vertical, subject centred and filling the frame height, the stool's legs fully visible on the floor, generous space either side. Lighting: soft key from the front-left, low contrast, gentle soft-edged shadow to her right, even fill on the face. Text inside: none. Constraints: never stand her up, never lower the raised knee or take the foot off the rung, never square her fully to the camera, never crop the stool legs, never add footwear, never add jewellery, never darken the backdrop. Output: 3:4 vertical.
