The young girl with blonde hair and blue eyes stands out against the page with her colorful outfit. Her strapless pink dress is a simple but glamorous look that is complemented with a white belt and matching pink shoes. To bring even more life to the drawing, you could color the background with a gentle gradient of pastel blues and pinks, making the girl stand out even further. For her outfit, a cool combination of pink and white would be pretty and effective. You could also draw attention to her face by making the hair a slightly darker shade of blonde and the eyes a bright blue. Finally, adding a light touch of blush to her cheeks and a swipe of lip color would finish off her lovely appearance.
