very good, but the hands look like they go a bit too far in, rather than being at the sides (hip) he looks like he's grabbing his stomach. Have you already expiremented with it? (found out it looks better this way?) if you haven't, just adjust it in different ways, see whether or not it looks better. Otherwise it's great; nice, smooth animation, and you managed to have a red emote without it being too dark and dull or too bright and overpowering. (I never can get red to look right)
You've animated that quite well . It's very smooth, especially the hand movements. The expression works well, giving that feeling of frustration. The red however looks a tad bright to me. Perhaps tone it down just a tad? I'm not sure about that really.
