Children's picture-book contest

Now, I'm not really into fiction writing... and I don't write for children at all.... at least, I never have before. But now I've decided I'm going to write a little children's book to submit to Sylvan Dell Publishing's children's book contest (PDF file). It'll be something new, anyway, and who knows? I might even, by some miraculous coincidence, win the thing. It's open only to currently homeschooled high-schoolers, so pass on the info! (Oh yeah - SDP's normal website is http://www.sylvandellpublishing.com.)
