儿童涂色书古典建筑立面

Generate a cartoon-style image for a coloring book for kids, featuring a building facade from around 1900 with a ratio of 9:11. The image should resemble the work of cartoonists Franquin and Hergé, with thick lines and low details, and no shading. The building should be of a classic style from around the turn of the century, such as Victorian or Art Nouveau. The image should be suitable for children to color in with crayons or markers. The building should be front-facing, and the facade should be simple enough for kids to color in easily, but interesting enough to catch their attention. --ar 1:1 --m magic --s 750
