【Core Theme】
The "beautiful back" is the main visual core, using backlighting, side backlighting, and soft light to highlight the shoulder and neck lines, shoulder blades, spinal line, and back curves. The focus of the image is the back, not the front face.

【Character Setting】
Adult female, temperament options: gentle / cold / lazy / mature / artistic / high-end. The characters should be real and natural, no plastic feel, no exaggerated makeup.

【Clothing Setting】
Clothing can be replaced freely, but it must serve the "backless structure" and "sense of emotion," such as: backless dresses, suspender dresses, tulle, knitwear, slipping shirts, silk long skirts, etc. Materials should be soft, layered, and able to participate in the composition.

【Posture Requirements】
Back to the camera, looking back, side profile, head down, raising hand to tidy hair, leaning, semi-reclining, etc. The posture should be natural, with the focus on displaying the back lines and body curves.

【Scene Setting】
Optional: window side, bedroom, bedside, chair side, homestay, hotel, minimalist room, city night view, etc. The background should be simple and not overshadow the subject.

【Lighting Requirements】
Focus on backlighting, side backlighting, and window light, emphasizing back contours, highlight edges, and light and shadow layers, making the overall sense more cinematic and breathable.

【Composition Requirements】
Vertical composition, the character is the absolute protagonist, the visual center of gravity is placed on the back and body curves, the composition is restrained, clean, and high-end.

【Image Style】
Realistic photography feel, cinematic feel, soft mist feel, delicate skin texture, shallow depth of field, naturally high-end, quiet and private.

【Restrictions】
No text, no watermarks, no logos, no e-commerce feel, no AI plastic feel, no limb deformities, no vulgarization.

【Final Effect】
A high-completion female portrait with "beautiful back + backlighting + emotion + clothing changes" as the core.
