黄金周结束屋顶日落

Create a melancholic anime-style illustration showing 18:00 at sunset, capturing the feeling that Golden Week is ending and work begins again tomorrow. The scene is a quiet urban rooftop viewed from behind a solitary young adult man, standing near a waist-high concrete parapet with a black metal railing, hands in his coat pockets, looking out over the city. He has messy dark brown hair and wears a long taupe trench coat, dark trousers, and black shoes; his posture is still, heavy, and contemplative, suggesting resignation and post-holiday sadness. The rooftop foreground has cracked concrete slabs, small weeds growing from seams, stains, and weathered walls. Beyond the railing is a distant city skyline in soft silhouette, with apartment blocks and office buildings dotted by warm glowing windows. The sun is low on the horizon, a pale golden disk partly hidden by buildings, casting an orange gradient sky that fades upward into muted beige. Include exactly 7 visible birds in the sky: 1 large bird silhouette on the upper left, 5 small birds grouped loosely in the upper-right-middle sky, and 1 tiny bird farther right near the edge. Use cinematic composition with the figure centered slightly below the horizon, expansive empty sky above him, warm sunset backlighting, soft atmospheric haze, thin clouds, subdued colors, delicate line art, painterly anime background detail, and a bittersweet mood of quiet loneliness and dread before returning to ordinary life.
