Using the uploaded photo as the reference, create a premium CEO-style headshot of the same person with a powerful and sophisticated executive presence. The portrait should be highly photorealistic and ultra-detailed, featuring direct eye contact, refined facial definition, and a confident, leadership-driven expression. Dress the subject in a perfectly tailored dark business suit paired with a crisp white shirt to enhance the luxury corporate aesthetic. Use cinematic studio lighting with dramatic Rembrandt-style shadows to add depth and authority, while keeping the background clean, dark, and elegant. The final image should have a polished, high-end editorial look with exceptional realism and 8K-level detail. Maintain a 4:5 portrait aspect ratio.
