A Copic marker-style anime illustration of a beautiful woman in a vivid red evening dress and matching high heels, lying flat and straight in a proper prone sniper position on a city rooftop at night. She holds a large sniper rifle mounted on a tripod, with her shoulder, cheek, and both arms positioned correctly to stabilize the shot. Her expression is calm and focused, hair pulled aside or flowing neatly behind her. The glowing city skyline stretches out in the background with scattered lights and a cinematic atmosphere. The artwork is rendered in a Copic-style illustration with hand-drawn ink lines, soft gradients, and warm tones that blend elegance and realism.
