Copyright rules for using S-117

I am in the process of writing a book on video games, and I want to use a fan creation of Spartan 117 Master Chief as cover art for the cover of my book. I don’t yet have the piece selected because I was going to host a contest for the artwork.

While I plan on making profit on the book, I don’t want to violate the Microsofts Halo copyright laws. So Is it possible to use a fan drawn image and not an in-game image on the cover, but then use some in game screenshot images inside the book? Since my book will have full color images and backgrounds in the book.

I just wish to have 343 and Microsofts blessing in using a fan made Halo/Master Chief image.
