Enhance Cartoon Illustrations for Children's Book

I'm looking for a skilled illustrator to enhance the details of a 20-page children's book. The book is set in a fantasy/adventure world, so the illustrations will need to reflect this.

Key Tasks:
- Improve the detail of existing illustrations
- Ensure consistency in character drawings
- Fix one character as per provided guidelines
- Match the style of provided reference images

Ideal Skills and Experience:
- Proficient in cartoon-style illustration
- Experience working on children's books
- Ability to follow specific design guidelines
- Strong attention to detail
- Previous work in fantasy/adventure themes is a plus

Please note, the target audience for this book is children aged 3-7 years, so the illustrations should be engaging and suitable for this age group.
