Art style: Vintage Storybook.
Full-length view, the entire figure visible from head to feet, standing upright and centered — Arisha, a cheerful six-year-old girl on the morning of her birthday. She has a round, rosy-cheeked face with big bright brown eyes, a small button nose and a wide gap-toothed smile. Her light-brown hair is medium length, gathered into two soft pigtails tied with cheerful pink ribbons, with a few loose strands framing her forehead. Slim, small child's build. She wears a festive lilac party dress with puffed short sleeves, a white lace collar and a wide sash bow at the waist, the skirt flaring softly. On her feet are white frilly socks and shiny buckled Mary-Jane shoes. She holds a folded paper airplane letter, glancing up with delighted curiosity. Behind her, a cozy sunlit bedroom with an open window and drifting balloons.
