First off, thank you Carla for putting these up! These are such excellent pictures and seeing these have certainly put me in a better mood today.
I really like the new looks of the villagers and the background.
Now, what can these pictures tell us? Arnie does have an excellent point. The first picture certainly does appear to be a room in a makeshift fort. There appears to be something like a chimney in this room and it seems like there is oil or paint or some other strange looking liquid on the ground... Now if this is a fort, why are they building it? Are they afraid of another tribe, or wild animals, or something else (maybe something with a magical element?)?
As for the second picture, (and I'm already surprised no one has mentioned it) what is with those faces in the wind/clouds to the left of the raft? It looks like a male and female are blowing the raft to the right but they're looking to the left. Hmmm....
Oh well, we're just going to have to wait and find out when it comes out! I can't wait!
