She has subtle makeup, highlighting her natural beauty.\n\n**Pose and Attire:** She is leaning gracefully and comfortably against an ornate, dark wooden railing of a traditional Chinese building. Her right hand is delicately poised, gently touching a large, vibrant kite. She wears a stunning, richly textured **deep blue silk cheongsam (qipao)**. The cheongsam is adorned with intricate and vibrant **pink and crimson red floral motifs**, likely peonies, cherry blossoms, or other traditional Chinese flowers, showcasing exquisite embroidery and subtle brocade patterns that catch the light. The fabric should show a subtle sheen and deep textural detail.\n\n**Headdress:** An elaborate and colorful **headdress crafted from fresh, vivid flowers**, including lush, velvety roses (in shades of pink and red), delicate lavender lilacs, and perhaps smaller complementary blossoms, artfully arranged in her hair. Each petal and leaf should be distinctly rendered.\n\n**Prop (Kite):** A large, traditional Chinese kite with a prominent, rich **blue background**. It is beautifully decorated with playful and detailed **pink koi fish motifs** swimming across its surface. A pair of strikingly large, expressive eyes are painted on the kite, adding a touch of whimsy. The kite's material should appear slightly translucent and textured, showing the delicate framework beneath.\n\n**Background:** The interior of an ancient, richly textured traditional Chinese wooden building. The backdrop features intricately carved wooden beams, decorative lattice windows or screens, and aged wooden wall panels. The atmosphere is **dimly lit and cozy**, with warm, soft light filtering in from unseen windows or lanterns, creating subtle highlights and deep, inviting shadows. Focus on the authentic grain of the old wood and the fine details of the carvings.\n\n**Lighting and Style:** **Hyperrealistic portrait photography, extremely high detail.** The lighting should be soft, directional, and atmospheric, emphasizing the textures. There should be a shallow depth of field, with the woman and the kite in sharp, exquisite focus, while the background gently blurs into a warm, cozy ambiance. Emphasize the tactile qualities: the smooth sheen of the cheongsam, the soft, velvety petals of the roses, the delicate, papery texture of the kite, and the aged, rough grain of the wooden structures. Cinematic lighting.\n```"
