夕暮れのビーチで貝殻の城を作る好奇心いっぱいの子ども

A child with wide, curious eyes playfully building a castle from glistening seashells on a hidden, secret beach. The sun is setting, casting a warm, golden light across the sand and sparkling water. This scene is captured in a soft, dreamy storybook illustration style, with gentle brushstrokes and a pastel color palette, evoking the innocent wonder of childhood adventures and fantasy.
