夏の海辺の線路のそばでピアノの鍵盤を歩く少女

An enchanting, whimsical storybook watercolor illustration visualizing Joe Hisaishi's 'One Summer's Day'. A serene summer scene showing a shallow ocean railway with water touching the tracks, where the train tracks seamlessly transform into glowing white piano keys. A young girl in a white summer dress walks along the piano keys under massive, fluffy sunset cumulus clouds. Floating glowing music notes and yellow sunflower petals drift softly in the coastal breeze. Soft golden hour light, masterclass watercolor washes, granulated paper texture, charming storytelling composition, 8k quality, masterpiece.
