Molino de agua

// «Molino de agua» · gpt-6-sol (medium)
// A small watermill seen from the front with its WATER WHEEL in clear view on the FRONT-RIGHT side (facing the viewer at -y or at +x, never hidden behind the house): a big round wooden water wheel almost as tall as the house, made of two rings of dark brown wood connected by many flat paddles around the rim and spokes to a central hub on a horizontal axle going into the wall, its lower part dipping into a strip of blue stream water running past the house. The house: stone ground floor, cream plaster upper floor with dark timber beams, red tiled roof, small wooden door and windows. Make the wheel the most noticeable thing.
