This animation like the others, is unstable. It looks like their bodies are moving for no reason at all, and tom opens his mouth when dan is talking. And you shouldn't ever be in a rush to animate, that's the opposite of what it is. If you ARE in a rush, stop animating and come back to it when you can. Don't just whip something up in a short period of time, and rush out, because that's just bad, and it is bad. Try harder, don't rush, EVER, and put your heart into it, this has none of that.
