Vertical 9:16 anime-style sky in ultra-detailed 4K resolution. A vast, painterly sky stretches endlessly, filled with massive, textured clouds in complex folds, subtle contours, and soft ridges. Gaps between the clouds reveal patches of light blue sky and warm sunlight beams filtering downward. Below, a winding stone path leads through misty hills toward a dark, towering castle with sharp spires piercing the sky. On the path stands a lone female swordfighter—inspired by Saber—clad in gleaming armor, her sword faintly glowing, and her flowing cape caught in the wind. She gazes determinedly ahead, ready to face the challenge. The atmosphere is dreamy and emotional, with pastel tones of blue, pink, and gold blending together. Soft bloom, watercolor textures, delicate cel shading, ambient haze, and layered depth create a nostalgic, cinematic mood, with dynamic clouds and fluttering cape promising strong motion potential.
