Elegant Birthday Celebration Portrait in Tuxedo

Ultra-realistic 4:5 celebration portrait of a young man in a classic black tuxedo, white dress shirt, and black bow tie, naturally smiling while holding a champagne glass. Use the uploaded photo strictly as the face/identity reference; preserve facial identity, proportions, expression, and overall appearance with high accuracy. Colorful confetti falls around him against a clean black background, sharply captured mid-air with shallow depth of field. Dramatic studio lighting highlights his face and upper body, creating a warm, elegant luxury-party mood. High-quality editorial photography, 4K detail. Add “happy BIRTHDAY” behind the subject in the upper background: “happy” smaller, elegant calligraphy, subtle gold; “BIRTHDAY” large, bold uppercase, off-white, clearly prominent.
