"Create a realistic illustration of a modern house, nestled on the beachfront with its foundations resting on golden sand. The house should feature a contemporary design, with large glass windows providing stunning views of the ocean. To add a touch of luxury, include a beautiful red Ford Mustang and an apple green Lamborghini parked in front of the house. Ensure that the cars are depicted with realistic and vibrant details. Additionally, add a cat sitting at the front door of the house, giving it a warm and welcoming atmosphere. Create a small ranch adjacent to the house, complete with a stable and paddock, where the horses can roam freely and relax. Ensure the image is in 4K resolution and extremely realistic, capturing every detail of the architecture, landscape, and surrounding environment. Finally, paint the sky with the warm hues of a magnificent sunset, adding a magical ambiance to the entire scene. This illustration should evoke the luxury, comfort, and tranquility of modern coastal living."
