Emily,
Thank you for a very fresh video! I liked the MinutePhysics-like hand-drawn look, and it is cool to see a high school student taking the time to convey the fun of physics to the world!
May I make a few suggestions if you ever do an updated version or a follow-up? YouTube viewers are usually impatient and will click away if your video doesn't instantly grab their attention, so a 20-second title intro, like you have, might be a bit too long. On a more sciencey note, when your draw your 2-D Jane and Tom, you should put their mouths and eyes on the side of their head, not in the middle... since they are 2-D creatures, they cannot see or eat the way you drew them! :):)
I hope your video does well in this competition!
Marc
P.S. If you have a chance to view, comment and vote on my trilogy of videos entitled "This Is Physics" --- where I try to convey the "fun of physics" by focusing on some of the greatest moments of its history --- it would be quite appreciated!
