A large thought bubble with a simple children's picture book illustration inside: a plastic bottle lying beside a street drain, rain falling, water washing the bottle into the drain, the drain connected to a small stream, the stream connected to a river, the river flowing into the sea. All elements are shown clearly and separately but connected by flowing blue water, easy to understand for kindergarten children. Scandinavian illustration, Dille and Kamille aesthetic, gouache painting, flat painted colors, matte palette, soft aqua blue water, sage green details, warm cream background, simple houses, simple clouds, minimal scenery focusing on storytelling, not landscape. Visible hand-painted brush strokes, visible ink outlines, slightly imperfect hand-drawn lines, European picture book illustration, gouache on paper, not a map illustration, not an aerial view, not a fantasy landscape, not an infographic, not hyper-detailed, not realistic.
