DM you are an artist to the core, but if someone is being critical of your work ad you want them to like it (if it's just one special person) show them a few sketches and ask them what they think conveys that mood, she'll tell you what she wants to see, but what you can never do is feel you "failed" on any picture. No progress you make is a failure, no step forward is a step back, every time you moved, something has happened.
Ask her opinions of what she feels "freedom" is and take her advice, then you will make the picture she wants, but I thought you did great
Never be afraid to ask that person what they really mean.
