The backstory is fascinating, but the art is amazing. You really have a flair/talent for detail and dramatic posing. Coloring is beautiful and the whole thing just radiates this wildness and passion--the curve of Snape's neck, his hand in Harry's hair, the way their lips are not quite engaged yet, and especially how Harry seems to be sitting the seat of a hero, possessive and claiming.
When I saw the genre you chose to represent, I knew you'd come up with something really extraordinary and intriguing and excellent, and I was right! Full marks and them some (virtual votes, of course).
