Cinderella stands in a dramatically lit room with a large clock looming behind her. She looks worried, her hands resting on her hips, her delicate figure silhouetted by the light. Her dress is a deep blue, with a neat white collar, and a white apron over it. She has her hair pulled back into a neat bun and holds a simple blue headband around it. To bring out more of the details, try shading around the clock in cool greys, which will highlight the warm, yellow hues of her dress. The deep blues of her dress can be delineated with a bright, light blue. Finally, bring out the lightness of the collar and apron with whites and creams. To finish, draw attention to her worried expression with subtle hues of brown and yellow.
