I just watched it.
So far, okay. The problem is that it's too wordy and while the background music is fun, it doesn't direct people to read the content. One thing that might make this better is to lessen the wordiness on each individual page and use some form of presentation logic to either generate messages, or when longer messages are displayed have them narrated.
As an informative video, this works fine; but what you're asking about is promotional. This means that you must hook people's attention and then keep it as the video plays.
