It looked like a school project, something about making an advertising about drunk-driving. That was an easy subject.
Sad you didn't add sound at all. You should have put something on, even a simple song, just to entertain our ears while we're watching.

Try again and put more effort on it, even if you have to wait for your speakers to be repared.
