create artwork for book cover

I am looking for a talented artist who can create cartoon artwork for the cover of my children's book about sharks. The book is about two siblings (boy and girl) that go on an underwater adventure in an "aquabuggy" to learn more about sharks. The ideal candidate will have experience in creating realistic illustrations and will be able to capture the beauty and detail of the underwater world.

Skills and experience needed:
- Proficiency in creating realistic artwork
- Strong understanding of composition and color theory
- Experience in illustrating children's books
- Ability to bring characters and scenes to life

I am expecting 1-2 revisions to ensure that the artwork aligns with my vision for the book cover.
