Design a premium, highly attractive children's educational book cover for ages 2–4. The title is "My First Shapes Book" in large, bold, playful lettering at the top. The cover should have a bright white background with colorful, friendly shapes scattered across the page. Feature a large smiling red circle, blue square, yellow triangle, green rectangle, orange star, pink heart, purple diamond, and colorful oval, each with cute cartoon eyes and happy expressions. Arrange them in a fun, balanced composition that looks educational and exciting. Add soft clouds, small stars, balloons, confetti, and a rainbow in the background to create a joyful preschool atmosphere. Use vibrant but clean colors (sky blue, sunshine yellow, apple red, grass green, orange, and pink). The design should feel modern, professional, and trustworthy so that parents immediately recognize it as a high-quality learning book while children feel excited to pick it up. Include a small subtitle: "Learn • Trace • Color • Play" Leave space at the bottom for the publisher logo. The overall style should be cute, friendly, colorful, educational, and suitable for a bestselling preschool workbook. The cover should look like a premium children's book sold in major bookstores, with clear readability, high contrast, and a joyful learning theme. Use vector-style illustrations, smooth lines, and high-resolution print-ready quality. No clutter, no dark colors, and no overly complex elements. Focus on making the cover instantly appealing to both parents and young children.
