Based on the uploaded photo, create a formal business profile portrait poster. Preserve the person's real identity features, facial proportions, face shape foundation, and overall temperament. Do not change the person's identity. Slightly optimize facial contours to make lines clearer, more natural, and photogenic. Smooth skin texture, reduce blemishes, dullness, and uneven skin tone, but avoid over-smoothing — retain real skin details and natural lighting. Design a matching business hairstyle based on the face shape: clean, neat, mature, professional, suitable for formal occasions, with natural layered hair strands, not exaggerated. Dress the person in formal business attire: dark suit jacket, white or light-colored shirt, optional tie. Overall look should be premium, clean, professional, and trustworthy. Front-facing half-body portrait, person centered, looking directly at the camera, with a natural and confident expression. Pure white solid background, soft and even lighting, similar to professional ID photos, corporate headshots, or university official profile photos. Clean, formal, business, high-definition photorealistic photography style. Square aspect ratio 1:1. Reserve a clean information bar at the bottom with modern minimalist typography: First line: name in dark blue bold large English text 'Yuzuna Koizumi'; second line: position in black regular English text 'Senior Graphic Designer'; third line: department in black regular English text 'International Design Institute'. No Chinese text in the image. --ar 1:1 --v7 --style raw
