I have a 'full' round face. My hair is 'mixed', I'm black and white race. It's THICK and wavy.?

I do have a CHI that I straighten my hair with or I wear it curly. What would be the best hair style for me? Also, I'm thinking about partial highlights (I have a coupon). I have blonde highlights in my deep dark brown hair now, but they're almost out. My hair is shoulder length. Any suggestions would be great. I can never find pictures of people with hair like mine- so I don't know what to try!!
