Its very simplistic. There a few things you should touch on. Some of these are;
The camera angle. The camera seemed to shake a bit much. If you wanted to imply they where talking you could of at least gotten actors. Its not that hard. And don't tell me it was because you had one person. I made
this with one person. That one person being me.
The HUD. You should really get the HUD hider or camera mode off RtB. It is really useful. It removes the HUD from the screen so you can record without it being in the way. I use it for all my videos and strongly suggest you use it.
Other then that, its nice. I like the voice overs. What did you use for it? Just curious.
