A playful and vibrant underwater scene created for a children’s “make & play” activity book. This illustration features cheerful sea creatures including an octopus, clownfish, dolphins, tropical fish, and a starfish surrounded by colourful coral reefs and ocean plants. I used bright colours, friendly character expressions, and layered textures to create an engaging composition that feels fun, lively, and inviting for young readers. The design was created to spark curiosity and imagination while maintaining a clear, child-friendly visual style suitable for educational and interactive publishing.
