Would you change anything in Harry Potter Book No. 7??? If so, what would it be?

Was there something that didnt hit you right or something that needed to be changed?? I thought it was perfect. I would have loved a little more conclusion on other people, like the Hogwarts Professors, the Weasleys, Luna, the Death Eaters, the Dementors and so on....I heard JKR is going to write an encyclopedia on such subjects so that will make me happy. Also, I wish I could have heard more about the rejoicing of the wizarding world and the rebuilding of the ministry of magic after the word spread of Voldermort's defeat. So what was missing for you?
