Don’t bludgeon us over the head with description. A line or three about the character is good enough—and it doesn’t need to be purely about their physical looks. It can be about movement and body language. It can be about what people think, about what goes on in her head. But throw out a couple-few lines and get out. Dialogue is where a character is revealed. And action. What a character says and does is the sum of her being. It doesn’t need to be more than that: a character says shit, then does shit, then says shit about the shit she just did. In there lurks infinite possibilities—a confluence of atoms that reveals who she is.
