Cartoon Illustrations for Brain Science Book

I'm looking for an illustrator with a knack for cartoon style drawings to create between 10 to 20 images for a non-fiction book about brain science. The ideal freelancer would hold an interest in both science and art, with the ability to effectively meld the two together into engaging visual content. Experience illustrating for educational or non-fiction books would be a huge plus, as it's essential the illustrations accurately represent complex scientific concepts in a fun, easy-to-understand format. Please provide examples of previous work in your bid, especially any pieces related to science or education.
