Problem
I created a character name and concept for a children's book on my own. I asked an artist to draw the character. I liked his illustration. I then wrote the book with the assistance of my brother. After my brother and I wrote the book we decided to copyright it. I copyrighted the book with all 3 of us listed as the Authors, and all 3 of us listed as the Illustrators. The only drawings the artist contributed at the time of the copyright was that of the two main characters. I have run into problems with the artist and do not want to use his illustrations any longer. However, I do want to get another artist and finish the children's book. The literature has been completely derived and written by me and my brother. The artist did not contribute one word or thought to the writing. Just as I did not draw any of the pictures. Although, I did explain exactly what I wanted for the drawing to the artist. What legal right does the artist have to the work and can I continue to use my concept and character name for that book and others? If you need more information I will be happy to provide.
The response should include a reference list. Double-space, using Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
