I wonder maybe the hood gets warped out later in the movie, I can't see figuarts making the hood so flared out on purpose
From what I've heard, Lucasfilm/Disney isn't even letting companies see the movie or parts of the movie for making the toys. According to Sphero, they couldn't get information on what BB-8 is like in the movie because it was all so hush hush. Sphero claimed they'd have to wait until after the movie was released before they can add more features to their BB-8 toy. I doubt it is any different with these Star Wars figures.
