Affiche de fête nationale avec soie vermillon et ciel bleu limpide

Theme direction: A minimalist National Day cover poster with an Eastern Zen aesthetic. Style variation: A bright, feminine, highly shareable National Day visual. Main subject: A traditionally styled woman stands beside the edge of a white elevated platform, raising one hand as she looks toward a long piece of vermilion silk gently lifted by the wind. Emotional motif: Brightness, joy, optimism, and mountains and rivers beneath clear skies. Scene and imagery: An ivory-white platform, long vermilion silk, a clear blue sky, a few golden osmanthus branches and leaves, the woman, and extremely faint distant mountains. Composition and space: Vertical 9:16 format. Position the woman toward the lower-right portion of the image. The vermilion silk enters diagonally from the upper right, forming a clear visual path. The sky and white wall occupy roughly two-thirds of the frame. Preserve a complete title area toward the upper left. Use the distant mountains only as an extremely subtle spatial layer. Color control: Use ivory white as the bright spatial foundation. Apply clear-sky blue to the sky and a small amount of distant atmospheric depth. Restrict vermilion to the windblown silk and a very small number of local accents. Use osmanthus gold for a few branches, leaves, and details. Keep the woman's clothing moonlight white or pale apricot white. Create a vivid yet clean festive contrast among red, blue, and white. Avoid covering the image with red or gold tones, and do not apply a warm color filter. Lighting and texture: Bright natural light on a clear National Day morning, with transparent air and crisp contours. Give the white platform clean highlights. Preserve the silk's thin, translucent quality and natural folds. Use the look of a contemporary Eastern graphic poster with only a slight paper texture. Aspect ratio: 9:16. Additional requirements: The festive atmosphere should be distinct without resembling a traditional propaganda poster. Do not include fireworks, streamers, crowds, complex architecture, or a large red background. Give the woman slender, natural proportions and a relaxed, extended pose. Keep the overall image high-key, low in gray tones, light, and transparent, with an unmistakably feminine aesthetic and the highly shareable cover appeal associated with Xiaohongshu. Place only a small Eastern calligraphic title and smaller text in a modern Song-style typeface within the negative space.
