Nice site!
The homepage is nice and you succeeded in making me interested into the site. I don't like human sites much, but I like how they are in the form of little smilies. Definitely a good theme for a site!
The Winter Tribe adopt is my favorite so far. I can't wait to see new features and adopts in the site since I like what I see so far.
I'm just wondering, who are you in the site? Are you some person from a different planet or some kind of creature? You never really explain it in the site. (And boy those adopts are happy for what happened to their kind. x3)
