Okay, I know these books are graphic, but you will not be allowed to submit art which contains these elements:
Images of hardcore sex/nudity
Images of rape
However tasteful nudity will be allowed, not porn or down right trash, which will be rejected.
The same applies to prose and poetry. Please keep it tame.
Gore and blood will be allowed, as long as it has something to do with the books and contains a warning.
Also, if you draw characters or use extracts from the book, please add a copyright notice ( e.g Characters © Jean M Auel) in your dev description, or you will not be allowed to submit your work.
