It`s a contest. Why don`t you pretend the Cow Judges are utterly (make that, udderly) a piece of the rest of the public? Either give them something good and a good example, or give them something winningly good, (hint, or just winning), and win. Anything from Pteradactyls slapping their wings together, to the lastest beat will do, as long as it`s the category I just put above. Submission length and content are good questions for self but submitting something a whole hour long sounds much too long. On the other hand, putting in a little story that rips people out of their chairs and sucks them in like the carburettor vacuum of a freshly gone- over Plymouth wouldn`t hurt. Plan if the, your, contest entry has a next use.
