"An elegant architectural sketch of a modern sports complex, featuring a large central stadium, surrounding arenas, and outdoor courts. The design should have a sleek, futuristic feel with clean lines and minimal shading, showcasing multiple sports facilities like cricket grounds, tennis courts, and a swimming pool. Emphasize the main stadium with a well-designed grandstand and seating, with trees and pathways around the complex. The sketch should resemble a blueprint, with a mix of perspective views and top-down layouts. Include some light annotations or measurements to give it an architectural feel."
