Heh, I guess my sense of Werewolf is quite illogical and bias. I do not know much of the history of Werewolves, but I have an affinity for ones "own inner werewolf" we are all capable of. Personally, I follow these ideals of the way of the Werewolf (fictional):
-A transformation of physical nature into a anthropomorphic bestial wolf being.
-Bloodlust, rage, hunger and freedom to let loose.
-Animal like nature and instincts, wanting to attack, eat, consume, maim but with a sense of sadistic nature. A killing machine.
-An elongated snout with large fangs, it is a A+ for me
-Longer, grasping claws is a plus too
OR...
If we are talking more literal here, in the sense of what can be more so achievable in the "Real life" perspective....then:
-The transformation of ones inner psyche to represent that of what a presumable (if real werewolf) was to be born into ones mind. Eg. A socio/psychopath with a more bestial instinctive nature.
-A human who is given wolf-like blessings, skills and powers given to those who have a human form, but with the mind of a werewolf/bestial being, eg. Heightened smell, bloodlust, hunting capabilities and insight etc
My personal tastes for Werewolves has been a fascination of both bestial fascinations, and that of my own inner demons or as one would call "Werewulf" (that's the spelling of his name). Deep down inside, as crazy as this sounds, we all are werewolves, its a matter of what you want to call your inner "form" inside your head. Physically we don't change, but we have the capabilities of being "another person" "evil" "sadistic" "a bad person" or such. This is why, the red werewolf I keep drawing, is symbolized as my own inner werewolf (Although he is actually more so a demon).
Sorry, starting to get abit off topic here X(....

But anyway, any other ideas?
... Any concepts would help, I might try what you linked before, of a wolf infront of a moon. I tried to draw it on a smaller scale awhile ago, but it turned out horrible X(...I'll see if I can make it a bigger resolution.
