一對情侶在宏偉建築的階梯上，以水彩素描呈現，線條輕盈，色調溫暖

提示詞

Create a beautiful watercolor travel sketch of a person in a bustling European street. The artwork should look like it was painted in a real travel sketchbook using watercolor and fine black ink.\n\nUse loose expressive ink lines, soft transparent watercolor washes, visible textured watercolor paper, natural paint bleeds, light splatters, and unfinished sketch details. Keep the architecture and background airy with minimal detail while making the subjects the main focus.\n\nCapture a candid, joyful moment with natural expressions and relaxed body language. Use warm daylight, muted earthy colors, soft blues, beige, cream, light browns, and subtle peach tones. Leave plenty of white paper visible to create a clean, elegant composition.\n\nThe final image should feel nostalgic, peaceful, romantic, and handcrafted, like an artist's travel journal filled with beautiful memories rather than a polished digital illustration.
