Create a single 9:16 cinematic dance portrait still. Show an adult East Asian female dancer in a sleek modest black contemporary dance outfit, centered in a modern minimalist white studio. Capture the source's sword-dance-inspired rhythm as one polished key pose: confident cold-elegant eye contact with the lens, clean fingertip gestures moving from the cheeks toward a fixed point near the chest, one sharp upper-body cutting gesture, a grounded stance that suggests full-body rhythm, and subtle motion energy around the hands. Use realistic movie texture, crisp facial detail, natural skin texture with soft luster, clear bright eye light, soft ring light on the face, gentle side light outlining the arms and shoulders, natural color saturation, stable centered framing, refined studio shadows, and high-end fashion dance photography. Keep the image performance-focused and elegant, with no video timeline text, logos, source-site marks, AI app marks, UI chrome, readable text, watermark inside the artwork, QR code, URL, sexualized framing, body exaggeration, underage appearance, distorted anatomy, or copied celebrity likeness.
