Japanese Castle Town and Lake Fantasy Anime Background AI Image Prompt

Using REFERENCE_0 as a rough childlike layout sketch, transform it into a highly detailed, polished fantasy anime landscape illustration. Interpret the simple gray drawing as a large Japanese castle on the left foreground, the blue outline as surrounding water or moat, the green mountain lines as lush forested mountain ranges in the background, the green jagged shape as islands or shoreline across a bright lake, the brown grid shapes as fields and town blocks, and the cyan lines as a broad blue lake or river. Preserve the overall spatial arrangement from the sketch, but replace all crude marker strokes with an expansive aerial panorama. Style: vibrant high-resolution Japanese anime background art, Studio Ghibli-like atmosphere, intricate architectural detail, crisp sunlight, rich greens and blues, soft mist, sparkling water, painterly but clean. Scene additions: create a fortified castle town with many traditional tiled-roof buildings, stone walls, bridges, canals, docks, small boats, sailboats on the lake, tiny roads and courtyards, dense forests, scattered islands, distant layered mountains, white summer clouds, and patches of low morning mist. Use a wide elevated viewpoint looking down over the castle town and lake. Constraints: no visible sketch lines, no text, no modern objects, no people as the focus; make the final image look like a complete professional fantasy background derived from the reference composition.
