What should i do with my hair?

hi there:) im 16. i have light to medium brown hair. its natural. i like it. but im thinking about getting some highlights. what do you think about blonde and red highlights? would that look nice? i have brown eyes:) if you need a visual look up kelly clarkson images on google. theres a picture that has highlights of the same description. so tell me what you think leave it natural or go for the highlights:) thank you in advance!
