Love the colors, concept of the full moon (I spy that little entropy mark in there, that will come as a surprise if the image ever gets srunken down to card size)
I love the light patches too, and the slow light to dark, circular progression.
The thing I see is that the style is different to others, and it looks very...realistic, more from a movie than from elements. Dark and Grungy looking would be a good place for the game to go in terms of artwork, but that seems far too realistic, and painful or sorrowful for the human/lycan. (Honestly, that makes the artwork stand out, and makes it a little deeper, and I think it's awesome because of that - it just doesn't seem to fit, like a tuxedo at a nightclub)
Most of my complaints stem from the humanoid shape, the hair, ears, mouth all seem a little too realistic, and in fact, I almost think of gorillas when I see it.
I'm trying not to sound like too much of a dick, because I actually really of like it in a twisted, "ooh it looks like a human gorilla...owww" kind of way.
And yeah, the layout, colours and theme is all perfect for elements art IMO, and is done really well, but when I look from that and look at my brother/friend/parole officer, it seems a bit...over the top. Maybe a bit more of a painted look, or softening of the features, making it a little less human and more beast is the way to go, in terms of fitting in.
(Even though, secretly we both know that tuxes are better)
