Create an image of a sad man sitting on a park bench during sunset. He has his head down, looking at the floor, with slumped shoulders, expressing melancholy. The square is partially empty, with some trees in the background and leaves falling. The man is wearing a dark coat and is leaning forward slightly., as if he were immersed in his thoughts. Soft evening light illuminates the scene, creating a dark and introspective atmosphere.
