Hand-Drawn Wedding Couple Invitation

Create a horizontal 16:9 hand-drawn wedding invitation illustration in a soft Korean/Japanese watercolor children’s-book style. Use a warm terracotta-red rounded rectangle background with rough dry-brush edges on a white canvas, subtle paper grain, tiny white sparkles and floating hearts. On the left half, draw exactly 2 cute chibi-style wedding characters: 1 groom and 1 bride. The groom has groom_hair_color softly tousled hair, a black suit jacket, white shirt, rust-red tie, gentle dot eyes, rosy cheeks, and a small boutonniere. The bride has bride_hair_color hair in a soft updo, a delicate flower crown, sheer veil, off-shoulder white wedding dress with translucent sleeves, dot eyes, rosy cheeks, and holds a bouquet of coral, peach, cream, and green flowers tied with a red ribbon. Include exactly 4 main floral decorations: the groom’s boutonniere, the bride’s bouquet, a lower-left floral sprig near the couple, and a right-side floral cluster with a large pale rose and small blossoms. Add a delicate decorative wedding name frame on the right half: thin white ornamental lines forming a loose rounded rectangle, a small heart at the top center, a bow flourish at the bottom center, and two blank name lines separated by an ampersand, reading “left_name & right_name”. Add exactly 1 decorative bow motif in the upper-left corner made from thin white lines and dotted floral ornaments. Keep the composition airy and romantic, with muted pastel colors, soft pencil outlines, watercolor blush shading, no photorealism, no harsh shadows, no extra people, and no watermark.
