Okay, we really didn't need to see the Ron one. I don't know about you, but that Ginny one seemed kind of hot. I'm picturing one of the Suicide Girls from her description.
I disagree, Hermione would have done one. The only thing is, it would have been so long and detailed that it would have ended up either singling out someone, or eliminating all possibilities. You should have done a Luna one anyway.
Here's a start for Hermione... exhibitionist bibliophile, seeking interesting visits to the library after hours...
For Luna...slightly damaged, can see creatures that you can't, prone to kidnapping crushes (you should know where that one came from),
Well damn, you never wonder if your day can get worse, because it will.
This is a story that you should definitely continue.
