I liked the way you healed Snape's injuries, that was clever and different. I loved the red curtain with the jingly brass rings, and I loved Snape's new Patronus, and the fact that Harry had appropriated his original doe.
Lots of other things to like here, too, including the little pictures interspersed throughout. Quite AU at times, but I do like your Snape and Harry quite a lot, so I was happy to imagine them both dancing along to a muggle punk rock band and liking each other so much. :D
