A medium shot, 3/4 view of Artoria Lancer on a bright outdoor tennis court, captured from a dynamic angle. She is a young woman with long blonde hair tied back, possessing an athletic build and a determined expression. She is dressed in professional tennis attire, consisting of a white polo shirt and a pleated white tennis skirt, with white athletic socks and sneakers. She stands in an active sports pose, firmly gripping a tennis racket with both hands, poised as if ready to return a serve. The background features the detailed texture of a hard-court tennis surface with crisp white boundary lines, a high net stretching across the mid-ground, and a clear blue summer sky above. The lighting is bright and natural, mimicking high-noon sunlight with sharp shadows and high contrast. The color palette is dominated by clean whites and vivid blues, with a clear, crisp visual style and a high-energy, competitive atmosphere.
