Some critique:
You spent the first 45 seconds talking about the channel itself, and when you were done, it sounded like you didn't know what to talk about. To be honest, you didn't sound entirely prepared to make this. I'm not saying that everyone should have a script, but there were a lot of "uh, yeah," moments. In the long run, despite sounding like that, you still explained how the Ortega method works. After all, that is the point of the video.
I hope I don't come across as a jerk.
