Realistic Illustrations for Children's Book

I'm looking for an illustrator with a knack for realistic styles to bring my children's book to life. The book is aimed at the 8-12 years age group, and will require between 11 to 20 illustrations. Ideal candidates should have a strong portfolio of similar work and experience in children's book illustration is a plus. Creativity, attention to detail, and the ability to interpret the story visually are key.
