Create a highly realistic freehand exterior sketch of a modern villa in black and white. drawing should be absolutely made by hand. The design should capture the villa’s architectural features with precise detail, including its sleek, minimalist façade, expansive floor-to-ceiling windows, and a sophisticated mix of materials such as concrete, wood, and glass. Showcase architectural elements like cantilevered upper floors, a flat roof, and integrated outdoor spaces such as a terrace or patio. Render the sketch with fine, detailed hand-drawn lines to accurately depict the building's structure and materials. Include realistic shading to highlight light and shadow, enhancing the depth and dimensionality of the scene. Surround the villa with meticulously drawn landscaping, including mature trees, well-maintained shrubs, and carefully designed garden areas. Add figures of people engaged in various activities, such as individuals relaxing on the terrace, walking in the garden, or interacting with the space, to provide a sense of scale and liveliness. Ensure the sketch reflects a true-to-life representation of the villa and its environment, with a focus on realistic textures, proportions, and spatial relationships, while maintaining a sophisticated freehand style.
