How to start another conversation with her on Facebook?

[ISEESTARS!]

Ok so Last night I was talking to this girl I met last week at the school football game,so im talking to her on Facebook,my friend Nate says she's really kool so I'm trying to be friend with her,Its went pretty well so far,but I dont want this to Be the only time I talk to her,so can someone tie me some advice on how to start another conversation with her,thanks
By the way,I don't have a crush on her or anything,I have a girlfriend named Arin,she's one of the most amazingly beautiful girls in the world and she's my best friends and I love her like crazy

Just "like" one of her recent pictures and then send her a private message saying something like "Hey, you know the photo that I just liked? You look great there, you should put it as your profile picture."

I wouldn't be friends with this girl, if I were Arin I would ask questions. Wait for the footy girl to message you next.
