A charming, retro folk-art style illustration of coral reef. Drawn in a naive, blocky, children's book aesthetic using digital wax crayon, dry brush, and gouache textures. The central subject is placed on a solid, softly textured aqua background block that has rough, uneven, hand-drawn edges. The background block sits on a raw white watercolor paper canvas. Include small, simple, naive botanical accents like leaves or seaweed floating around the subject. At the very bottom, beneath the colored block, include the hand-lettered text "Coastal Club" in a childish font. Soft, muted, cozy Mediterranean pastel color palette. Flat composition, no shading. --ar 70:99 --raw --stylize 88 --hd --profile i7s5756
