Chibi Angel Girls at Sunset

Create a heartwarming square anime illustration with a background of a grassy riverside slope at sunset. Three chibi-style angel girls sit side-by-side on the slope, knees drawn up to their chests, facing forward, with small, beady eyes and gentle smiles. Each girl has a glowing headband and a pair of small white wings on her back, totaling three headbands and three pairs of wings. The girl on the left has {argument name="left character hair color" default="Long light blue hair"} She wore a light blue zip-up track jacket with white stripes, a dark pleated skirt, striped knee-high socks, and light blue sneakers. The middle girl possessed {argument name="middle character hair color" default="Long blonde twin tails tied with black ribbons"} She wore a dark green zip-up track jacket with white stripes, a black pleated skirt, striped knee-high socks, and yellow-accented sneakers. The girl on the right has {argument name="right character hair color" default="Long pink hair"} She wears a coral pink zip-up track jacket with white stripes, a white pleated skirt, striped knee-high socks, and pink-accented sneakers. The background employs a cute and softly lined 2D anime style, featuring warm, nostalgic lighting, rounded proportions, clean silhouettes, and delicate grass textures dotted with white daisies. The left side of the background includes a staircase leading up a slope, while the right side shows a calm river reflecting the orange sun. In the distance, there is a bridge and a city skyline under a peach-orange sky and scattered fluffy clouds. The overall atmosphere should be tranquil, fantastical, and slightly magical, with the sun low near the horizon, and the grass and water shimmering with warm golden light.
