A portrait-oriented, waist-up photograph

A portrait-oriented, waist-up photograph of subject (man) has perfect facial details as reference image, with a neutral, subtly smiling expression, looking directly at the camera. He wears a loose-fitting, long-sleeve black button-down shirt with an open collar and dark buttons, paired with blue denim jeans. His arms are crossed over his chest, with a silver chain bracelet visible on his left wrist. The lighting is soft, diffused outdoor daylight, providing even illumination on the face with natural, slightly warm skin tones. The background is heavily defocused, featuring a pale grey building with dark rectangular windows and blurred green foliage on the left. The image features a shallow depth of field characteristic of smartphone portrait mode, sharp focus on the subject, slight corner vignetting, and a natural, slightly matte color grade.
