Very interesting relationship development here. It was a bit heartbreaking when Harry rejected Severus' need for more contact, but yet Severus was able to piece together what was driving that and didn't take it as a flatout rejection. That's nice growth from canon. I really liked how Severus started to reach out to Minerva, even Ron and Hermione a bit. His "revival" is what made the story for me (and I was glad to see Harry's as well).
I like the dreamy, 40s-style to the first piece on the nightclub and the loneliness of the second piece, but the picture of Dumbledore's tomb in the snow is my favorite. It's so peaceful; it really reflects where the characters are at that point.
