This is really a good tutorial. I guess when it comes down to it, we all do a form of dynamics when emoting. It's called body language. We don't just stand stiff as stone, speaking our minds. Also, great to show how a body can betray an emotion. For instance: A hostage in a bank must remain brave, but his fists are clenching; seeing the robbers punch a woman to shut her up.
Thank you SO much for this snippet of information- lately I've been giving out about a million critiques and I have redirected about 3/4 of them to here because you explain is so simply yet so well! Thank you very very much!
