Create a cozy square anime illustration at sunset on a grassy riverside embankment. The scene features exactly 3 chibi angel girls sitting side by side on the slope with their knees hugged to their chests, facing forward with small dot eyes and gentle smiles. Each girl has one glowing halo above her head and one pair of small white wings on her back, for a total of 3 halos and 3 wing pairs. The left girl has long aqua blue hair, a turquoise zip-up tracksuit jacket with white stripes, a dark pleated skirt, striped knee socks, and teal-accent sneakers. The middle girl has long blonde twin tails tied with black ribbons, a dark green zip-up tracksuit jacket with white stripes, a black pleated skirt, striped knee socks, and yellow-accent sneakers. The right girl has long pink hair, a coral pink zip-up tracksuit jacket with white stripes, a white pleated skirt, striped knee socks, and pink-accent sneakers. Use a cute soft-lined 2D anime style with warm nostalgic lighting, rounded proportions, clean outlines, and detailed grassy texture dotted with small white daisies. In the background, include a stairway on the left climbing the embankment, a calm river on the right reflecting the orange sun, a bridge in the distance, and a small city skyline under a peach-orange sky with scattered fluffy clouds. The atmosphere should feel peaceful, whimsical, and slightly magical, with the sun low near the horizon and warm golden highlights on the grass and water.
