Sticks and Stones
Good for a first attempt, but not likely to get into the portal because it's a stick movie basically. I'm sure this took you a while but it needs to be slighlt longer, have better graphics and maybe even a story line. You could also try making a sprite movie, there's loads of good sprite sites. Sprite movies are quite easy to make and have more chance of surviving in the portal. So hope this helps! :)
