One more thing about the Shinji film. If you can freeze frame him in an underwater shot as he turns his head to breath, look at his spinal alignment. I would almost suggest making a hard copy of that picture and posting it on a full length mirror. Try and stand in front of the mirror in exactly the pose that Shinji has and you've got it.
Here is my version attached
