Good job.
The animation in that was really good, it was definitely an improvement from your TF 2 lip sinc test, but don't know how much effort you put into that, so it might be an unfair comparison. Still, good job on the animation. How long have you animated?
I did notice an error or two though. First, right before that guy ran off the cliff at the end of the first part, he turned white for a second. Not a big deal, but just something I happened to notice. The other thing I noticed (although it was more likely intentional than an error) was how the arm of the guy holding the lamp was contorted in an awkward position when he got that "dramatic look" on his face.
On another good note, I think you did a really good job with the scene transitions. There is a really smooth transition between the games.
Lastly, I like how you put a heavy (pun not really intended) emotional feel of sacrifice on the Tean Fortress 2 part. I never really think much of people dying in front of me (or blowing up Medics and/or Heavies) but tou almost made me feel bad.
Overall, you're pretty good at this and I'll be sure to watch your stuff in the future! Great work!
