Im thinking it is the model because when I tried rendering scorps statue, everyone was complaining about how he looked like he was leaning back in the win pose. When I compared it to the original statue I needed to edit the arms to make them thicker yet not as long and the head larger. Anyway at this point I think we are nitpicking. If you can adjust the camera to reduce that shrinking in the torso area then great, but I'd rather you kept moving on the animations instead. Then once they are all complete we can make one global camera edit and rerender if really necessary.
