I'm talking to this girl on facebook, what should I say next?

[534]

Ok, I found this girls facebook randomly it was unbelievable but I think she is the most beautiful thing I have ever seen. She lives on the other side of england so it wouldn't be appropriate for me to go and see her yet.
Any way I sent her this message last night:
Me: 'Hi, sorry we haven't met before, I just added you cause you're really beautiful, I hope that's not weird :L'

She replied to it this morning saying:
Her: 'That's fine! Aw no that's not weird, it's a compliment! Thankyou x

I replied when I found it a couple hours later saying:
Me: 'Your welcome, that's good aha x'


It says hasn't seen it yet, but I sent that message 4 hours ago, what should I say next? Should I wait for her to reply? Or should I try and get her talking? I know this may seem a bit stalkerish but I would really like to get to know her.
