A smiling young european male bartender wearing a white shirt, black vest, and red bow tie, stands behind a bar counter. He is shaking a stainless steel cocktail shaker with both hands, mid-motion, looking to the side with energy and joy. On the bar in front of him: a red cocktail in a cocktail glass with a garnish of dried lime and mint, a large glowing red buzzer button, a white bottle dummy, and a digital stopwatch showing “00:20”. The background features softly lit liquor shelves with colorful bottles, slightly blurred to enhance focus. Warm, inviting lighting with pink-violet accents reflecting. Vertical framing, photographic realism, clean and dynamic composition. Perfect for an interactive event rollup.
