The coloring page depicts a young girl standing against a light blue background. She has fluffy, light brown hair pulled into two buns on the top of her head. Her clothing is simple yet stylish, with a white tank top, a yellow and green striped skirt, and a matching yellow and green striped scarf around her waist. On her left wrist, she is wearing a white bracelet. In her right hand she is holding a bright green tennis racket. To bring the image alive, you could use bright, bold colors. For the girl's outfit, you could use different shades of yellow, green, and white to make the stripes on the skirt and scarf stand out. To make her skin tone look natural, use a range of skin tones with light pink highlights. For the light blue background, try some subtle shading to give it depth and warmth. Finish off your work with some detailing like highlights in the hair and shadows around the body for a vivid final result.
