Gray studio triptych

Photorealistic natural fashion studio vertical triptych, three stacked horizontal panels of the same fictional 20-year-old adult Japanese woman. Minimal light-gray concrete wall and smooth gray floor. Strong natural sun from the left, sharp shadows to the right. Cute Japanese-idol-like adult face, medium-brown hair in a small messy bun, soft wispy bangs, loose face strands, natural makeup, pores, slight asymmetry. Simple black bra-style top with thin straps, loose oversized black wide-leg or cargo trousers, black high-top sneakers, delicate necklace. Tight framing so she fills each panel.
Top panel: sitting sideways on the floor leaning back, hands behind for support, torso long, head turned aside, head to calves or shoes.
Middle panel: kneeling or sitting low, knees apart, both hands on the floor in front, torso leaning forward, closest crop emphasizing torso.
Bottom panel: casual sit leaning back, one knee bent up, one arm behind, gaze slightly to camera, showing bent leg and sneakers.
Same wall, sun and shadow in all panels. No UI, no text, no icons, no watermark. Adult woman only.
