Nautical Anime Line Art Colorization

Using the provided reference image, apply a full-color anime illustration style to the line art. Transform the character into a high-quality digital painting with soft shading and vibrant colors. Set the color palette to a nautical theme: use navy blue for the vest, skirt, and boots; cream white for the shirt sleeves and satchel bag; and warm brown for the hair. Render the background as a bright, sunny coastal train interior with deep blue seats and a view of the ocean and Mount Fuji through the windows.
