Harbor Twilight Photo Sketch Poster

Goal: Create a refined vertical travel-and-architecture poster that combines a realistic twilight harbor photograph on the top half with a hand-drawn architectural concept sketch of the same scene on the bottom half. Canvas: Portrait poster, 3:4 aspect ratio, clean editorial layout. Divide the image into 2 horizontal sections: the top photographic section occupies about the upper 52% of the canvas, and the bottom cream-paper sketch section occupies about the lower 48%. Top section: Show a serene place_description. The scene includes calm blue water in the foreground, warm yellow streetlight reflections stretching vertically across the water, a stone harbor wall on the right, a pier and breakwater on the left, hillside houses with glowing windows and streetlamps, dark layered mountains in the background, and a deep blue dusk sky with scattered clouds and a faint pink sunset band near the horizon. Include exactly 3 visible boats in the harbor: 1 larger white fishing boat near the center-left foreground, 1 small boat moored near the center-right, and 1 white boat at the right foreground. Use realistic photography, cinematic blue-hour color grading, crisp detail, and tranquil atmosphere. Bottom section: On warm off-white textured paper, recreate the same harbor as an architect’s concept perspective sketch. Use fine graphite construction lines, loose ink outlines, watercolor washes in soft blues and grays, and selective warm golden highlights for lamps and reflections. Keep the sketch aligned with the photo above: mountains in the back, village and harbor wall on the right, breakwater on the left, and boats in the water. Include exactly 3 sketched boats matching the top section. Add thin vertical and horizontal perspective guide lines, measurement-like marks, and faint construction strokes around the buildings, boats, horizon, and reflections. Typography and text: In the lower section, place a large elegant serif title on the left reading “poster_title”. Beneath it, add small widely spaced uppercase subtitle text reading “subtitle” with a short thin divider line. At bottom left, add small uppercase text reading “COASTAL VILLAGE\nSTUDY SKETCH\nJAPAN” with another short divider line. At upper right of the sketch area, add tiny stacked uppercase words reading “PLACE\nPEOPLE\nLANDSCAPE\nA BETTER DAILY LIFE”. At bottom right, add a loose handwritten signature-style note reading “Same Sea\nA Kinder Tomorrow”. Visual style: Sophisticated Japanese coastal poster design, calm minimal composition, premium paper texture, elegant negative space, architectural visualization aesthetic, natural perspective, delicate watercolor, warm lamp glow, and harmonious blue-and-cream palette. Constraints: Do not add extra boats beyond the 3 specified. Do not add people as major subjects. Keep all text legible and placed only in the bottom sketch section. The top must remain a realistic photo-like scene while the bottom must clearly be a concept sketch of the same view.
