Elegant Carnation Mother's Day Wallpaper

Create a minimalist vertical Mother's Day wallpaper poster on a warm ivory paper background with soft natural shadows and lots of negative space. In the center, arrange a delicate bouquet of carnations with 5 visible flower heads: 1 large pale pink carnation near the upper left, 1 closed pale pink bud at the upper center, 1 peach carnation in the middle, 1 soft yellow carnation on the right, and 1 pink carnation near the lower center; include slender green stems, narrow leaves, and 3 small green buds, rendered as realistic pressed-flower photography with gentle studio lighting. Overlay very large elegant black Japanese calligraphy reading main Japanese word across the upper-middle of the bouquet, then place a refined high-contrast serif headline across the lower-middle reading main headline, with thin Didot-style letterforms and graceful curves. Add 4 small letter-spaced message blocks in black: top left says top left message, top right says top right message, bottom left says bottom left message, and bottom right says bottom right message. Keep the composition airy, elegant, feminine, modern Japanese editorial style, with crisp typography, realistic flower texture, subtle shadows, and a premium greeting-card aesthetic.
