Oh god, your language, your metaphors, the synesthesia of your descriptions. These images will stay with me for a very long time. For instance - your depiction of Snape in the forest of Dean: black shadows on the ivory snow and Snape, stepping over them, brushing musical chords with his robe. His interaction with the doe patronus. The almost kind of beauty permeating every ugly scene. The hand-cradling in hospital. Books and Snape's cottage in general. The cruciatus.
When Snape touched Harry's head in the Shrieking Shack I literally choked. Your writing is exquisite. And I'm in love with Snarry again.
