Serene Mid-Autumn Lantern Poster

Goal: Create a serene vertical Chinese festival poster about {argument name="festival theme" default="Mid-Autumn Festival"}, combining vast twilight scale with an intimate human moment.

Canvas: Tall 9:16 portrait poster, cinematic painterly realism, soft atmospheric depth, no border or watermark.

Layout: A symmetrical central-axis composition. The top third is dominated by exactly 1 large glowing round paper lantern suspended from a thin cord, positioned slightly above center. The middle contains vertical Chinese title typography. The bottom third shows a distant ancient town and mountains at sunset, with exactly 2 silhouetted human figures seated on a stone terrace railing in the foreground.

Main focal object: The single oversized lantern is warm golden-yellow, nearly circular, softly luminous like a moon. It has visible paper ribs, subtle fabric/paper texture, a decorative lower rim, a small top cap, and exactly 1 orange tassel hanging beneath it. Add delicate branch-and-blossom silhouettes printed across the lower left and lower middle of the lantern. The lantern casts a gentle halo into the cool blue-gray dusk sky.

Foreground narrative: At the bottom center, show exactly 2 people from behind: 1 older adult and 1 child, both small and dark against the glowing horizon. The child holds exactly 1 small round lantern on a short stick, glowing amber. They sit quietly on a traditional stone balcony or temple terrace with carved railing. Rooftop silhouettes frame the lower left and lower right corners.

Background environment: A layered ancient Chinese cityscape stretches into mist, with palace rooftops, pagodas, small warm window lights, rolling mountains, and a low golden sunset. The sky transitions from deep cool blue at the top to muted amber near the horizon, with sparse soft clouds. Emphasize calm, spacious negative space and gentle seasonal nostalgia.

Text content: Place exactly 3 text elements on the central vertical axis: 1 large vertical Chinese title with 4 stacked characters, {argument name="main title" default="灯映婵娟"}; 1 smaller Chinese subtitle line below it, {argument name="subtitle" default="今夜有月 也有归人"}; and 1 tiny English-and-Chinese festival line below that, {argument name="footer text" default="MID-AUTUMN FESTIVAL · 农历八月十五"}. Use elegant restrained Song/Ming-style Chinese typography in dark warm gray, thin letter spacing for the small footer.

Visual style: Poetic Chinese seasonal poster, quiet cinematic concept art, warm lantern glow contrasted with cool evening haze, realistic yet softly illustrated, refined composition, minimal clutter, contemplative mood, high detail in the lantern and atmospheric softness in the city.

Constraints: Keep the first visual read as the isolated circular glowing lantern in the large calm sky, then guide the eye down the central axis to the title, subtitle, terrace, and two figures. Do not add extra people, extra lanterns, modern buildings, bright neon colors, or additional text.
