For example, I know the 180 rule, but it's hard for me to work out how to balance between speakers. When to have a shot with both speakers, and when to look, say, over the shoulder. I can recognize that you don't want a single static shot of two people talking to each other and I can copy some scenes I find, but it's all just guesswork for me on why they decided to do what was done. Also, I don't yet have a good sense of determining what things ought to translate from real life and what doesn't animate well. (I tried to mimic a Lord of the Rings scene and it was pretty dry

Even pointers on how to animate the head, while talking, so that it's neither still, nor wiggling all the time would be helpful. For example, I get that you want to emphasize key points in a sentence, but does that mean it should be at the apex of a head move or what? Strong heavy emphasis is easier to understand. Simple and subtle interaction is harder for me.
So even youtube examples of what you think are high quality animated dialog focused scenes would be helpful. I could at least use them as examples.
Thanks for any suggestions.
