Transform the provided image into a detailed, stylized 3D world map designed for a fantasy role-playing game. Preserve the geographical layout and general features from the original image where appropriate, but render it with an overhead isometric perspective, a vibrant, slightly painterly aesthetic, and clear geographical details. Incorporate a charming medieval village with thatched roofs amidst rolling hills, and a bustling harbor with wooden docks, small ships, and a lighthouse along a distinct coastline. Ensure rivers, mountains, and forests are clearly depicted in the stylized 3D map format.
