Toon Real Children's Book Illustrations

We are working on a 10 page children's book, which is to be produced using vector. Each "page" is a double width A4, with characters on the left hand side and text on the right. The book will of course need a front and back cover also. The book is a story of a parent's journey from pregnancy to the day they meet their newborn. The book will be personalised, so users can add their own cartoonized faces such as those attached, which will be used for the characters within the story.

We will need this produced in AI, from which an SVG file for each page is required.
