I am lurkin in this thread for quite a long time, have had a break lately and now come back, browsing through the latest posts... First, I love most of the art here. even the crude sketches - as far as they relate to WoW. But I really have a problem with Rachel's art.
It's great from the perspective of technique. It's great from the perspective of imagination. But it deviates away from WoW (yeah, pun intended) in a way that I find mildly disturbing. It looks to me that the artist takes the theme of WoW and bends it to his own wills and desires so much, that the consistence breaks. Kind of a mild (or not that mild?) abuse of the setting.
New critters are OK, but, for example, Rachels interpretation of the dreanei is too much for me. (And I have no problems with any kind of deviations from normality, in fact, in my fiction world I am creating as a fantasy writer, I have a bunch of hermaphroditic, asexual and whatsoever characters just to explore different possibilities and mindsets, because it fascinates me). But I would never try to bend the world and setting of WoW to my fantasy that much. It does no credit to the creators of this world where I have been partly at home some years ago.
