Pretty good video!
I can also add that doing loose gesture sketches and dynamic poses can also help with both of these. Sometimes, bodies in motion aren't exactly "pretty", but that's ok! It helps get that gesture across!
It can also help to add different stylish effects or artistic mediums/styles like charcoal or cubism. Something that makes out of your normal routine but gets you that gesture and feeling you want to come across for your audience. I do that sometimes myself!
