You certainly deserve the love and praise. You did a lovely job of mining a very well-used character and revealing hidden depths. And it was wonderful as well, to see this Snape in an AU where, being stripped of all the devices and trappings of magic and his history, the psychology of his character drove the story.
Another aspect I loved, albeit a minor one, was that in the HP universe its not always remembered the stature Snape has in his field. What you did by giving Snape such a prestigious occupation and high-profile standing in this story, was correlate what his true level of accomplishment was back in HP land. I think it often gets overlooked that Snape is actually quite a brilliant man, and a highly accomplished and powerful wizard. What he doesn't get in canon is recognition--thank you for rectifying that a bit!
Anyhoo... I, along with many others, loved this wonderful story. It's been keeping residence in my head ever since I read it, and welcome. You couldn't have given us a better gift!
