What do girls like in a Guys Facebook Profile Picture?

Hi i got a new facebook cause i got hacked before. I want a fresh new fb pp, so what do girls like? I dont want to brag, show off or be a tool. What do girls think is cute? I recently posted a picture of me playing the harmonica by a pond, and nobody really liked it. So i want something AMAZING? Any ideas? im a guy, and im not good at photography with photos. Should i get a cute Baby Pic of me? IDK what do girls like?
