I agree! Before release I was worried that "only" five regions would make for a limited amount of environments (compared to XB) but the exploration trailer and the game itself proved how wrong I was.
Regarding the characters... I have mixed feelings about the models. Some of them are pretty great, but others not so much. There is a scene at the last chapter, with Doug laughing in a way in which his face was REALLY creepy... but then you have others like Hope, Elma or Vandham...
Anyways, when you look at the original designs they are normally good. I mean, I would have loved an Irina 3D model more faithful to the original design:
So you can say that the designer isn't bad, but something happens in the transition from the art to the game.
PS: I'm not sure how the scans guidelines of the site apply in this case, if this isn't allowed please tell me and I will remove the image inmediately.
