The subject is posed in a three-quarter profile, wearing a [black turtleneck] and sleek [metallic accessories], with reflective [sunglasses] catching ambient light. Directly behind the subject, a [circular neon light ring] creates a luminous halo effect with crisp rim highlights along the head and shoulders.
