OMG. This is absolutely amazing. Snape's face, covered in shadow, those silent tears, wow. His grief is almost palpable. I can really feel it. Harry's glasses on the headstone make this all the more heartwrenching. And the rain. What a powerful image!
I've always loved your Snape but I think this one is my favourite. One of the sexiest Snapes I've seen! I can't stop looking, even though it breaks my heart.
