Anime Illustration Post-Golden Week Blues

Create a melancholic anime-style illustration set at {argument name="time of day" default="18:00 at sunset"}, capturing the mood of {argument name="holiday name" default="Golden Week"} coming to an end and work resuming tomorrow. The scene is a quiet city rooftop, viewed from behind a lonely young man as he stands beside a waist-high concrete parapet and black metal railing, hands in his coat pockets, gazing out over the city. He has messy short dark brown hair and wears a long {argument name="coat color" default="gray-brown trench coat"}, dark trousers, and black shoes; his posture is still, heavy, and contemplative, conveying resignation and post-holiday melancholy. The rooftop foreground features cracked concrete slabs, weeds growing from the gaps, stains, and weathered walls. Beyond the railing is the soft silhouette of a distant city skyline, with apartment blocks and office buildings dotted by warm lights. The sun hangs low on the horizon, a pale golden disk partially obscured by buildings, casting an orange gradient sky that fades upward into soft beige. The sky must include 7 clearly visible birds: 1 large bird silhouette in the upper left, 5 small birds loosely clustered in the upper middle-right, and 1 tiny bird near the far right edge. Use a cinematic composition, with the figure slightly below the horizon line and a large expanse of empty sky above, combined with warm sunset backlighting, soft atmospheric haze, thin clouds, low-saturation colors, delicate line art, and painterly anime background detail to create a bittersweet atmosphere of quiet loneliness and faint dread before returning to ordinary life.
