Manet
I know the site is about anime, and things related, but I think the art shouldn't be JUST people, and charectors, and things like that.
I'm an artist, but I don't do people. I don't think it's very fair that my art gets rejected.
Gaia is a an anime/fantasy themed website. As such, the admins created an art arena to mirror Gaia's themes, and so it features anime, fantasy, and sci fi related art only. There are many sites that are open to all kinds of art, including deviant art and shezzy art, if you wish for places to post all your art. However Gaia's arena is only for art that has the same theme as the site itself.
As for complaints regarding the AA in general: We're /well/ aware that the AA has a lot of problems. ^^; There are numerous changes that I personally would absolutely love to see done to it, however it is not high on Gaia's priority list of features to work on and develop, so we
all have to be patient, because it will not be changing anytime soon. As both a user and a moderator I am not happy with this either, however as there is nothing we can do about it, waiting is the only option.
