Anime Girl on Garden Bench

Create a soft, detailed anime-style illustration of a young girl sitting on a wooden park bench beside a calm pond in a lush Japanese garden. The girl is centered slightly left, with {argument name="hair color" default="warm brown"} hair in twin low pigtails tied with white ribbon bows, large gentle brown eyes, a small smile, and a peaceful, shy posture with both hands folded on her lap. She wears a light blue sleeveless dress with tiny white floral patterns, a white cardigan, tan strappy sandals, and a small pale yellow crossbody satchel. The setting is a bright spring or early summer park with dappled sunlight, dense green trees, flowering plants, grasses, lily pads, and a reflective pond behind her. Include exactly one wooden arched bridge in the mid-background crossing the water, exactly one small pavilion or gazebo on the far right bank, exactly one large tree trunk on the far left foreground, and exactly one small wooden sign at the lower left with simple Japanese characters and a pink flower symbol. Use a square canvas, warm daylight, soft watercolor-like rendering, delicate linework, rich foliage detail, sparkling reflections on the water, and a wholesome nostalgic mood. Avoid modern city elements, extra characters, logos, watermarks, or random added text beyond the small sign.
