is there anything i could do or say to make this guy feel more attraction towards me?

i'm a freshman and the boy i am interested in is a sophmore. i added him on facebook, and he doesn't seem to have any past girlfriends, but he's actually attractive and stuff. does that mean he doesn't think any girls here are good enough for him, he can't find anyone right, or what? and anyways, are there any cute comments i could comment on his pictures that aren't creepy or anything? and how could i talk to him? i go to school with him too. he looks at me a lot (as if that means anything, right?) are there ANYTHING that drives guys like insane and make them want someone really bad? i'm not ugly, not too sound stuck up... and i'm really nice. so yeah? haha help pleaase.
