I said that I would watch the videos and review them by tonight, and I did!
First, and this question is just directed at Erin for whenever she comes around: what two episodes were those from?
As for the review. Personally, I thought you portrayed the mood for both as rather serious, which is a good thing, considering that the series is rather serious. The actors have talent, (although I'm certainly not very experienced in acting, I have taken two acting classes and have performed in a few school plays when I was younger, so I have a basic understanding of acting) and I think that they portrayed the characters well.
I ask for the episodes because I like to know what context the scenes are shot in, because the only downside that I noticed was the second scene appeared to have a bit of monotone, with little voice expression. It did not seem phony, but it did appear a bit rigid. Again, the scene could have been designed for that, and if so, then I take back what I say. Overall, though, you did a very nice job on the videos. Keep up the wonderful work, and I can't wait to see the theme song incorporated.
