Generate a high-resolution, mixed-media image with a 3:2 aspect ratio, presenting a horizontal split for a side-by-side comparison of the Great Wall of China. The left half features a detailed technical sketch in a monochrome or blueprint blue color palette, showcasing precise architectural lines of wall segments, watchtowers, and defensive structures, complete with numerical metric measurements for wall height, width, and tower spacing, alongside elevation labels for wall sections and towers, and both side elevation and top-down layouts illustrating the wall's curvature along the terrain, all annotated with English text in a blueprint or engineering-style typography. The right half displays a high-resolution real photograph of the Great Wall, capturing a wide panoramic view of the wall stretching across mountains under natural daylight with a clear or lightly clouded sky, rendered in natural realistic colors that highlight the visible stone texture and the surrounding landscape. A vertical line or subtle transition divides the sketch from the photograph.
