A dramatic and serene anime movie poster featuring Harry standing in a simple, upright pose at the edge of the Black Lake. He gently holds his wand in front of him, presenting its light rather than casting a spell. A magnificent, fully-formed silvery stag Patronus emerges calmly from the tip of the wand, its head held high. The Patronus serves as the sole source of illumination in this moonlit scene, casting an ethereal, cool glow that highlights Harry's face, which radiates an expression of peaceful power and resolve. The background is a minimalist, inky-black landscape with faint outlines of dark trees and a misty lake, ensuring the brilliant silver light is the absolute focus. The style is clean, elegant, and powerful, showcasing incredible detail in the translucent, glowing form of the Patronus and the subtle textures of Harry's jacket. This masterpiece is of the best quality, in a 9:16 aspect ratio, with glowing effects, dark ambient tones, a monochromatic color scheme, and sharp focus --ar 9:16 --quality 4
