Blue-themed Birthday Celebration Portrait

Use the uploaded image only for face and identity reference. Preserve the subject’s real facial identity, face shape, skin tone, hairstyle, natural smile, and overall likeness accurately. Create an ultra-realistic 4:5 vertical birthday celebration portrait of a reference female subject standing indoors in front of a luxury birthday decoration setup. She is centered in the frame, shown from head to full dress, smiling naturally while holding a round blue birthday cake with white and blue cream flowers on top. The subject wears an elegant royal-blue sleeveless party gown with a glittery fitted bodice and a flowing satin skirt. Add realistic fabric shine, soft folds, premium stitching, and a graceful party look. She has long, softly curled hair styled over one shoulder, elegant earrings, and a very subtle glam makeup. Background: dark charcoal wall decorated with warm fairy lights hanging vertically, surrounded by a large balloon arch made of metallic silver, deep blue, and light blue balloons. Behind the subject, place a glowing neon sign that clearly reads “Happy Birthday To You” in bright soft blue-white light. Keep the sign slightly behind her head but readable. Lighting should be soft cinematic party lighting with a gentle glow from the neon sign and fairy lights, realistic skin texture, natural shadows, shallow depth of field, polished DSLR photography look, high detail, clean composition, premium birthday photoshoot mood. Avoid distorted hands, extra fingers, unreadable text, plastic skin, cartoon look, over-smoothing, messy balloons, wrong cake shape, extra people, harsh shadows, or AI-generated artefacts.
