Cinderella is feeling dejected and tearful, her head in her hands. The sadness is palpable on her face, showing that she's been crying for some time. She is seated on the ground and looks vulnerable. To capture the mood of the situation I would color Cinderella in earth tones to emphasize her sadness and loneliness. Her dress could be a deep, muted blue, while her hair a lighter shade. A gentle orange hue could be used to construct her face and make her eyes stand out. Some soft yellows, pinks and creams can be used for shading, with perhaps some brighter oranges added for a touch of warmth. With careful use of color the emotions in this scene can be truly brought to life.
