Well Odin would have been a tad more appropriate. I mean really, what does Thor have to do with Fafnir? I could also see Loki. But Thor? Might as well post a pic of Khumn, call him Zeus, and be done with it.
Anywho, that aside:
Nice hairdo, Faf. It has that sort of "I'm stylish enough to look good, but not too stylish to beat the crap out of you" look.
