First of all, please don't post pictures of people on the internet without their consent. Yes, she's cute. No, she probably doesn't want to be ogled at by a forum of people she doesn't know. Please remove it.
Second of all, she is going to notice that you created a facebook account just to talk with her. Depending on how close you were to each other, she will feel somewhere between surprised, annoyed, and seriously creeped out. Because it's a stalkerish thing to do.
Third of all, yes you are hoping this will go somewhere. Otherwise you wouldn't say "it's still the kind of look that I find attractive, that hasn't changed".
Fourth, if it's been five years since the last time you talked, this is not the way to renew contact. Yes, you might get lucky, but you are stacking the deck against you. Honestly, there's probably no good way to renew contact anymore. It's fine, life does this to people all the time, especially after school and college.
Fifth... there's probably other girls in Germany? Whose company is enjoyable in non-platonic ways.
To be fair, sometimes people get into you in ways you can't describe and that aren't rational, and they stay there for far longer than they should, maybe even forever. Heck, maybe you will still remember this girl while being in a relationship with someone else. It's confusing. It doesn't mean you should try to bring a sense of closure to the situation above and against common sense.
Obviously, you are free to do whatever you want. Try not to frighten her in the process. And/or severly taint your public image.
I hope I haven't been harsh? Just trying to bring an outsider's perspective.
