A cheerful mother duck plays with the flowing water at the edge of a calm river while her three tiny ducklings gather closely around her. The scene is drawn entirely in black and white using soft, clean linework without any solid dark areas or heavy shadows. The mother duck’s feathers should appear lightly textured and lively, while each duckling is illustrated with small, fluffy strokes that emphasize their cuteness. Ripples and small splashes in the water should be rendered with thin, delicate lines that keep the composition bright and suitable for engraving. Around them, the riverbank features gentle grasses, smooth stones, and subtle plant details that add a charming natural feel. In the background, simple trees, distant meadow shapes, or faint countryside elements create depth without overpowering the scene. Overall, the composition should feel joyful, warm, and visually captivating, highlighting the playful moment shared by the duck family beside a beautiful riverside.
