Whimsical Watercolor Illustration Generator

Please generate an illustration with a 【theme/subject】, overall in the whimsical childlike style of children's book illustrations: outlines with loose black ink lines to outline the outline, details are not overly realistic; Layered with soft watercolor grading and dotting, the colors are clean, warm, and slightly paper-textured. The visual style suits postcards, children's picture books, Christmas advertising campaigns, and emotional editorial illustrations, with a sincere, healing, and slightly nostalgic atmosphere. The composition is simple, with comfortable blank space, and the main character is clear and prominent. No photo texture, no 3D rendering, no overly sharp details. No watermarks or logos.
