Nicely done! I liked the use of graphics (names, numbers, etc...) to reinforce the point. I wouldn't be shy about cutting to a full screen image of info points to drive home what you're talking about. Good job!
Nice first effort! I would make three suggestions:
1. The audio is mastered too hot. The general level of audio should be around -18dBFS, allowing room for distortion-free peaks and agreeing with levels of other professionally mastered audio.
2. The HD camera is actually higher resolution than the virtual studio background. You should find a higher resolution background image, or blur it (in high res) so we don't see the aliasing in prominent curves.
3. The microphone is picking up the fan noise of the camera. (It sounds like soft--but noticeable--clicking.)
Again, for a first effort this is great. Fix one, two, or all three problems and your next one will be that much better!
