Hmm, that is interesting about the worn furniture. You would think Draco's parents would give him the money to buy whatever he wanted, given that they bought brooms for the entire Slytherin team just so that he could get onto the team.
I thought it was a Muggle camera Colin Creevey had and a special potion that developed the photos so that they would move, not a special wizarding camera. Although, of course, now that we are in the 21st century, we don't really develop photos any more or if we do, it's through those computery things rather than the way it was done in the 1990s.
It must be SO much more complicated for Muggleborns now than in Harry's day actually, with the internet and other technologies SO central to everybody's lives.
I like the way Harry's breakup with Ginny is mentioned. It makes sense for Harry. He isn't the sort of person who would go into work complaining about his wife/girlfriend leaving him.
It also make sense that Harry would die young. It's really sad, after he survived the war, that he would die later but still young, but being an Auror is a dangerous job, even in peacetime and Harry is the sort of person who takes risks.
Your ending is so sad.
