This fic made me smile so much. I love that you didn't try to make Snape fully alive, I love someone trying to take on the challenge, especially in such an unexpected way.
All the elements you brought together for this fic were just amazing, and I'm rather jealous of all Snape's potraits with different locations - would that it were possible.
I love Snape's friendship with Lily the younger and the heartfelt and detailed thoughts he gave on his friendship/hatred with everyone from the marauders era. I really like your Minerva for some reason too.
So many elements which came together for a fantastic fic. :D
