Arms and Roll Fingers

Roll fingers is tricky, as you have to set all axes in right position.
To animate them all the joints have to be aligned in the same direction.
The result is cool, they look like real fingers.

Also the arms are finished, the only problem there was the forearm, the effector have to be snap from the forearm to the wristle, in such a way that if you take the wristle joint all the arm can be moved.
