Of course there are things that can be done to improve performance, but in terms of expression without vocalization or speaking out the context, I think that the only way is to accumulate experience. When I look at my seniors, beside great acting skills, they also have a certain air that comes from their years of experience. I believe that there's definitely more to it than just technique. I think it all depends on how many different things I can accumulate in the future.
Danger Zone (Kenny Loggins) from Top Gun (1986) soundtrack doesn't leave from my head this days.
