A Dapper Birthday Toast Portrait

Ultra-realistic 4:5 aspect-ratio, celebration portrait of a young man wearing a classic black tuxedo with a white dress shirt and black bow tie, smiling naturally while holding a champagne glass in one hand. Colorful confetti is falling all around him against a dark black background, captured mid-air with sharp clarity and shallow depth of field. Studio-style dramatic lighting highlighting his face and upper body, warm and elegant mood, luxury party atmosphere, high-quality editorial photography, 4K detail, clean dark backdrop with floating confetti accents. Add the text "happy BIRTHDAY" in the upper background behind the subject: "happy" should be smaller, in an elegant calligraphy style, with a subtle golden color, while "BIRTHDAY" should be large, bold, uppercase, off-white color and clearly prominent.  Use the uploaded photo as the face and identity reference only. Preserve the same facial identity, facial proportions, expression, and overall look with high accuracy.
