You are a very good artist and I am sorry you are having difficulty with your teacher. You may want to rethink about telling her about where you place your drawing of her with (what she would see as) unkind words about her. It may not go well for you as she could make your life on-line miserable or off limits. Go over the scenarios of what could happen and if you want to live with these changes in your on-line life you will do what you will do. I believe you could come up with a better solution for yourself. I wish you the best.
I hope you keep drawing everyday and posting them on steemit to see your progress. You maybe be surprised. I especially love your style of drawing.
