Ultra-realistic 8K, high-definition portrait of an girl, based on a photo reference. She is standing or sitting gracefully, leaning slightly toward a birthday cake with a single candle shaped like the number 10 (only one 10) and "Happy Birthday" clearly written, smiling warmly at the camera, radiating joy, confidence, and enchantment. She wears a Mulan-inspired birthday dress, featuring elegant soft tones like red, pink, or gold, with flowing layers, subtle sparkles, delicate sequins, and fairy-tale princess details suitable for a young girl. Minimal, age-appropriate accessories like a small tiara, floral hair clip, or decorative fan. Her hair is styled in soft, voluminous waves or a gentle updo, reminiscent of Mulan's iconic look. She is surrounded by playful magical elements, such as floating lanterns, gentle sparkling effects, cherry blossoms, or balloons, creating a dynamic, adventurous scene. The background is a magical, storybook birthday setup, with soft ambient lighting, shimmering drapes, fairy lights, and whimsical decorations, evoking a cinematic, fairy-tale atmosphere. The portrait conveys innocence, elegance, joy, confidence, and magical celebration, with ultra-realistic cinematic lighting, high-detail textures, and a polished, fairy-tale finish. Keep her face exactly as in the reference and her body child-appropriate.
