Close-up vertical portrait of a young couple standing close and smiling

Close-up vertical portrait of a young couple standing close and smiling, both dressed in coordinated vibrant red outfits — the woman in a sleeveless V-neck red dress with a subtle rhinestone belt and long dark hair pulled into a loose high ponytail with soft face-framing strands, the man in a red button-up shirt and matching trousers with tousled dark hair, light stubble and wearing stylish dark sunglasses; warm celebratory background with golden balloon letters partially spelling "HAPPY," soft warm fairy lights creating creamy bokeh, a blurred dessert table and cake in the background; soft flattering front fill, subtle rim light for separation, shallow depth of field, sharp eyes and catchlights, natural radiant skin tones, cinematic warm color grading, high-resolution, slight film grain, crisp details on fabrics and hair, romantic joyful mood, three-quarter body crop, 85mm equivalent, f/1.8, low ISO, gentle retouching. 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.
