[Please check the contest entry at my DA journal for any updates, FAQs, and so on.]
Your mission, should you choose to accept it, is to go to Wintersweet's AutoShoujo Random Title Generator, pick a title, imagine a series/story based on that title, and to create a picture depicting the FRONT AND BACK COVER for either a DVD, manga, or book of the story you imagined. This should be your artwork, concept, and characters, not fan art or using anyone else's work.
The front cover should have the title you used on it, and the back cover should have a short blurb describing the story in such a way as to make people want to read or watch it. Look at the backs of manga, books, and DVDs to see how that's done. If the text is too small to read in the picture, also put it in the description.
