Children's book illustrations

Seven half-page illustrations for self-published ebook and print book, plus a full-page illustration for the cover. Depicting nature, buildings, and children in scenes as described in detail separately. The style should be naturalistic or comic-style, preferably light, natural colours. The book is about children and nature, so the pictures should not look flat or technical, but breathing and natural. Pictures needed soon for December launch date. This is a series, so I prefer artists who are interested in a long collaboration. In your answer please mention details of this description, or the keyword coffeeshop. I am not interested in generic answers that don't reference these requirements. Many thanks!
