Yeah, those are really good. Just try to make them as interesting as possible. They aren't always going to go viral...mine is an example of one that hasn't done well. I guess it's a little boring, but that just makes me see what can be improved next time. They will get better over time, and yours will too. Just don't give up, and get lots of feedback. Keep in mind, sometimes negative feedback is much better than positive feedback. That means you are hearing what your audience wants, and what they don't want.
