Sand Dollar Sea Urchin Marine Skeleton Pattern

Explore the delicate mathematical perfection of a sand dollar and sea urchin skeleton pattern. A large sand dollar dominates the center with its iconic flower-like pattern, surrounded by smaller sea urchin shells showing their intricate geometric lattice. The white calcium skeletons glow against a dark background. Composition: Center the sand dollar with smaller specimens arranged around it in a cluster. Light and color: Shell white, warm beige, deep shadow, and subtle blue-gray. Creative direction: Create a marine abstraction that celebrates the mathematical beauty of ocean life. Emphasize sophisticated form, material behavior, spatial depth, and a deliberate visual rhythm suitable for a premium digital backdrop. Keep one dominant visual gesture and clean negative space; avoid text, logos, accidental faces, muddy color, and repetitive noise.
