Affiche Botanique Estivale d'Ipomées

A vertical Chinese aesthetic summer poster in a soft watercolor and mineral-pigment print style, set on a warm ivory rice-paper background with ample negative space on the right. Composition: The left two-thirds are filled with winding morning glory vines rising diagonally from bottom left to upper left, featuring translucent green heart-shaped leaves, thin curling tendrils, pale stems, and a few unopened buds. The right third remains mostly blank negative space for vertical typography. Exactly one tiny pale blue butterfly flutters near the upper-right text area. Flowers: Exactly five prominent morning glory blossoms with glowing white star-shaped centers and delicate radial veins: 1 large pale pink blossom in the upper-left center, 1 small light blue blossom near the upper center, 1 medium lavender-purple blossom in the middle, 1 large sky-blue blossom in the lower-left center, and 1 small pale pink-lavender blossom in the lower-right of the vine cluster. Typography: On the right, elegant vertical Chinese calligraphy in a thin Song style reading "[夏日安好]" in muted sky blue. To its lower right, smaller vertical text reading "[清风与花影]" in muted olive green, with a small red seal stamp underneath and a very thin vertical divider line. Visual style: Airy, refined East Asian vintage botanical illustration, subtle granulation, gentle ink texture, no harsh outlines, pastel palette of sky blue, pink, lavender, sage, and teal. Calm, uncluttered, and non-photorealistic.
