That is just beautiful. Wow, I whispered when I saw it. Seriously. The soft detailing on the mirror frame, the statuette on the shelf, the fine glow of the runes on the ground around Harry's knees...I mean, all these things beyond that intense look on Snape's face and the exhausted fall of Harry's hair...and his back! It comes out so clearly that he's defeated, even though he's apparently succeeded in the task at hand. Wow. Breathstealing!
