OB半写实肖像画 - V2.1 细节增强

OBxiaoxiang, 
A thoughtful facial close-up of an elderly man, his face a map of life experiences, gaze directed slightly off-camera as if in deep reminiscence. The rendering imparts a profound, almost sculpted texture to his features. Soft, directional light from a single source creates gentle shadows that emphasize his wrinkles. The pale gray background has a texture resembling old, worn stone, adding to the contemplative mood. His eyes, though not directly engaging, hold a story, and the subtle texture of a well-worn wool scarf around his neck is evident.
