復古明信片風格插畫，描繪山丘與天空，採用色鉛筆與水彩繪製

提示詞

Using the provided reference image as the landscape base, transform it into a vertical vintage travel-journal postcard illustration. Keep the same countryside composition and viewpoint, but redraw it as a soft colored-pencil and light watercolor sketch on warm cream textured paper, with hand-drawn outlines, loose shading, and slightly faded pastel colors. Add a large blank cream margin above and below the illustrated landscape. At the top, add exactly 1 handwritten cursive title: Sunny Days, with a simple underline flourish. At the bottom, add exactly 1 smaller handwritten caption: — Good time —. Make the finished piece feel calm, sunny, nostalgic, and handmade, like a page from a sketchbook or rustic postcard. Do not add any people, vehicles, buildings, logos, or extra text.
