Create a square 1:1 photorealistic 2x2 portrait grid. The subject is [Subject Description]. Keep the same facial identity, age, facial structure, hairstyle, expression direction, and professional lighting quality across all four panels.
Top-left panel: [Profession 1]. Top-right panel: [Profession 2]. Bottom-left panel: [Profession 3]. Bottom-right panel: [Profession 4]. Each panel should be a clean professional head-and-shoulders portrait with a softly blurred background appropriate to that role.
Use high-resolution photography, natural skin texture, consistent face proportions, realistic clothing details, balanced color grading, and crisp panel boundaries. Avoid real brand logos, name badges with private information, extra watermarks, mismatched facial identity, different ages between panels, distorted eyes, warped helmets or collars, broken grid alignment, cropped faces, and low-resolution artifacts.
