A Dapper Birthday Toast

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. Insert discreet watermark in the lower right corner of the image, vertical text (rotated 90°), written "aipromptlabs.online", Calibri Light font, white color with low opacity (semi-transparent), medium size. Extreme sharpness on the face, fabric texture and typography of the letters. Shot on Canon EOS R5, 50mm f/2.8, studio light.
