Confident Man in Black and White Studio Portrait

Using the provided image of a man, create an ultra-realistic, highly detailed black and white studio portrait. Preserve all facial features, proportions, hairstyle, and facial expression. Maintain his confident pose: one arm bent and the other folded across the chest. The subject should be wearing a tight dark sweater and classic trousers, preserving the fabric texture, folds, and silhouette. Maintain soft natural lighting from a large window behind him, creating subtle highlights on the face and soft contrast on the clothes. Keep the background with a geometric window frame, ensuring a clean, minimalist, and elegant atmosphere. The final shot should have sharp details, smooth tonal transitions, realistic skin texture, and a classic premium editorial style.
