A very well-rounded story and perfectly in-character, including Luna. I like that Harry stayed in this new reality, knowing that both he and his other self would be happier with the trade. Harry was persistently in Snape's personal space, though what usually would spell disaster for most couples actually worked in thier favour. I like that Harry was secretive and cheeky, both are qualities that I saw in the books and I'm glad you carried them over here. You also had an interesting, and new, way of using Snape's mother to save him from death. And the whole concept around Malavar Crane was very inventive. I like the way you played with magic in this: the circus and snake-charming, the mirrormancy, Trelawney's creepy ways of fortune-telling, the polyjuice use, the concept of the inbalance Harry caused and its fix, all of it. You did a really great job with this!
