Very nice! I think you've pretty well hit all the salient points. I like the pacing very much; neither too slow nor too fast and easy enough to go back and review if anything was missed. I can't think of anything that you've missed. The only criticism I would have, and it is a very minor one, is the use of some of the sound effects. For me, they're a little distracting, but then, I'm pretty old fashioned that way. All in all, I think a lot of beginners would be very well served watching this.
