What type of haircut should i get?

I have a small forehead which kind of makes my cheeks look big :/, a round face, i'm 5'3'', 15 and a junior in H.S. Right now my hair is layered,medium length, and reallllyyyy thick ... I want to make my face look even by maybe covering my forehead with sidebangs? or covering up my cheeks to make them look smaller? I also want a hair cut that's right for my age. pictures and advice of what kind of haircuts/hairstyles would be nice. thanks!
