What are really pretty hairstyles for a grade 7 girl?

I already know how to straighten and curl my hair with a straighter. I know to do normal braid pigtail, working on french braid pigtails. I know to do a normal on french braid (the lauren Conrad look) my bangs. I know how to do a twisted messy bun. But I want to know other different hairstyles for medium layered hair that can take an hour doing. And of course that looks nice nad pretty. Thanks so much!!!!
