That is awesome! You chose every canon momen just perfectly, and the way you snipped them together was wonderful. Also, sneaky with the point of viewing to make it hotter than it was in canon, lol. Then again, every moment with Snape and Harry in the same room changed the temperature.
This was absolutely beautiful, and makes me so happy.
You know, I don't think there's going to be a person in fandom who doesn't know how to draw cervines soon.
