Winter Sports Coloring Book Illustrations

I'm seeking an illustrator to create images for a children's coloring book focused on winter and winter sports. The target age group for the book is 6-8 years, so the images need to be simple and easy to color, yet engaging and fun for kids interested in the winter season.

Key Requirements:
- Experience in creating illustrations for children's books
- Ability to design simple, engaging images
- Understanding of themes related to winter and winter sports and characters
- Skills in creating images suitable for a coloring book

Please provide a portfolio of similar work.
