Full, vibrant anime illustration of Katara from *Avatar: The Last Airbender*. The girl is depicted large, taking up most of the frame, and is fully visible from head to both boots; leave a small margin around the edges, do not crop anything. Beside her is a huge, fluffy white head of Appa, much larger than Katara, gently tilted toward her. Only Appa’s head is visible: kind, expressive eyes and his characteristic horns. Katara has a recognizable face, dark side locks, and blue ribbons. She wears a voluminous, soft blue coat with thick white fur trim, a straight, symmetrical short wrap skirt with neat overlapping panels, an elegant hem, and delicate embroidery of clouds and flowers. On her feet are blue low-heeled boots with fluffy white trim. Her hands are bare, no gloves or mittens, fingers clearly visible. In the background: a lake, a forest, and a clear blue sky; the background is secondary. Bright, saturated colors, carefully rendered soft fur, clean anime-style art, a warm, fairy-tale atmosphere. No text or speech bubbles.
