If you want to join in the fun, you could do something really simple. Don't worry too much about your current skill level. Just think of it as a great learning experience. In fact, I'm pretty sure I joined a competition only a few weeks after I started working with 3d. Besides, if you submit a finished project, you'll be much better than me, as I can't even remember the last time I've completed a project that I've posted on Simply Maya.
