Minimalist Travel Poster Design

Please use the real photos I provide to generate a travel photography poster with upper and lower zones, referencing the overall "city check-in / fridge magnet / minimalist collage" style.
[Image Structure] The composition is vertical, with a 3:4 aspect ratio. The entire image is divided into upper and lower parts.
The upper half occupies about 50% of the image and features a minimalist solid color background;
The lower half occupies about 50% of the image, preserving the original image without modification
[Top Part: Fridge Magnet Icon] Extract the most recognizable main element from the real photo in the lower half. Transform this architectural element into a minimalist "fridge magnet-style character icon."
1. Retain the core contours and iconic features of the character;
2. Simple and clean design, like a travel souvenir fridge magnet;
3. Slightly three-dimensional and projection;
4. Clear edges, white or light-colored outlining;
5. Simplify details appropriately; do not draw them too complicated;
6. The icon should be positioned slightly above the center in the upper half;
7. The icon is small and delicate, with plenty of blank space around the edges.
[Background Color] The upper part of the background color extracts the most important and memorable color from the photo. For example, the blue, yellow, red, green of the person's clothing, or the strongest ambient colors in the photo. The background should be solid, saturated, clean, and have a travel postcard feel. Do not use gradients or add complex patterns.
[Text Layout] Add a line of elegant handwritten English text below the fridge magnet icon: "{argument name="text" default="spicycandy"}"
[Overall Style] The whole should look like a high-end travel photography card: real photos + minimalist group photo fridge magnet + main color background + light text layout. The style is fresh, clean, bright, and gives a sense of city roaming. Emphasize recognizability, color memory points, and travel check-in atmosphere.
