I made a fake facebook account, and deleted it.?

Since you didn't use the other girls name and didn't commit any crimes using her photo as far as I can tell you didn't really attempt to "impersonate" her except by using her photos.

IANAL (I am not a lawyer) but I don't think 'borrowing' photos is a crime. Possibly, the original photo owner could attempt to go after you for re-use without permission but this would be a "tort" (a civil suit) not a criminal charge, essentially a kind of copyright infringement: which seems unlikely.

So you're worst downside is a civil suit copyright infringement type problem, and with personal photos - which have little commercial value - I think that's unlikely.

Just don't do it again.
