Um, wow. I think I'm going to be repeating myself a lot here, but suddenly I am very glad Champions can't vote. I'd hate to be giving all these top scores to the other team!
Where to begin? Even skipping over the technical mastery here, the whole concept behind the images totally blows me away. Knowing Harry, I can really see how his inabilty to recognize Snape for the ally he was while he was alive would eat Harry alive. And now there's no way he can fix his mistake. I'm sure it could haunt him for the rest of his days and you captured that madness perfectly.
This is just creepy, and poweful, and utterly brilliant.
