If you want a little more insight into the workings of my brain, here is a fun interview I did with Ryan Meehan of FirstOrderHistorians.com. Below is an excerpt:
RM: What’s the most crucial aspect of nailing down a great impression? Does it depend on the figure that you are trying to impersonate?
PK: Yeah, it does depend, but I usually start with how they hold their face. If there’s something strange they do with their lips or jaw, doing that will get you a long way towards having the impression. Also, not to get too technical, people from different cultures speak from different parts of their mouths. French people speak from the front, Scottish from the back, American and German from the middle. Getting that helps a lot too.
Thanks, Ryan! It was fun!
