I really love the lines! O_O Fenrir is one of my least favorite characters for his vulgar-ness, but I loved studying every inch of him here. *can't stop staring at his tummy* I think I've gotten so used to werewolves looking like actual wolves that seeing a wolf-man was refreshing. And I just love how his body is SO wolfish and feral yet human at the same time.
I agree with atdelphi that it takes a lot of artistic skill to provoke so much reaction and feelings from the audience. This picture did exactly what it was meant to do, in my humble opinion. One look at Fenrir and what he was doing made me hate him so, so, so much; it was like the first time him showed up in HBP and I wanted to throttle him! And I felt bad for the young Draco. Did you know Draco is my least favorite character ever in the series? I really don't care for him, and yet this piece evoked something tiny inside me, though briefly, but still! You managed to make a Draco hater have a temporary feeling of sadness and sympathy; I'm impressed! Consider that a job well done! :-)
