Comparing characters again

Anna was tall and slender, almost pretty, with those cold grey eyes and long neck and a puffy mouth. When she was sitting, her movements were relaxed and precise. When she stood, she seemed to be afraid of slipping in her high heels on the polished floor of the store floor and took short careful steps without the grace she had while sitting. She looked confident, until she started talking. Her voice wavered a little, but that made you aware of her youth and made you want to ask a senior consultant to deal with. She looked especially vulnerable when you began asking her something, as if she expected a tricky question at the exam. But then she'd gradually relax and tell you what you wanted to know. By the end of our meeting, when she handed us our printed agreement for signing, she spoke evenly, with more depth in her voice and more joy in her eyes.
