Travel Diary Poster Transformation

# Please convert the attached photo into a minimalist travel diary-style poster.
[Elements to Keep]
- The composition of the photo: buildings, walkways, the sea, people, umbrellas, stairs, etc.
- Keep building shapes recognizable enough to be identified.
[Art Style]
- Hand-drawn + silk-screen print style illustration.
- Shapes are significantly simplified; outlines are thin and slightly irregular ink lines.
- Bleeding watercolors, faded pigments, paper grain, and old print fading.
[Colors]
- Muted blue, sea green, beige, gray, terracotta.
- Background is warm ivory handmade paper with wide margins.
[Text]
- One line for the title in a typewriter font at the bottom.
- Below that, a small, poetic one-line caption.
[Prohibitions]
- Overly realistic depictions, cluttered arrangements.
- Gaudy colors, too much text.
[Output]
One vertical 4:5 poster. With the calm atmosphere of a seaside afternoon. Keep text minimal.
(Customize the title and quote as needed)
Title: "{argument name="title" default="harbour light"}"
Caption: "{argument name="caption" default="afternoon lingers in the curve"}"
