Generate an illustration of a young woman enjoying a summer day in the style of Hisashi Eguchi, with a clean and crisp line art, flat colors, and a slight retro manga aesthetic. She has short, tousled black hair and is wearing a white sleeveless top with a blue-and-white striped skirt. She is standing on a platform at a seaside station, with the ocean visible in the background. The scene captures a sense of movement and wind, with a bright and fresh color palette. The background includes a clear blue sky with fluffy white clouds and the sea, creating a light and breezy atmosphere, reminiscent of a moment captured in a video. The style should avoid watercolor textures and instead use bold lines and vibrant, solid colors --ar 1:1
