I know it may have looked out of bounds because people may have used the curved boundary line further around as a reference however the whole ball has to be over the whole line and it wasn't as proven below.
Proved what? Its a 2D picture. You have tried to add depth to it... but you cant... because its 2D. The ball is in his left hand, but your line connects to the right side of his shadow. I would say your line should be dissecting the boundary further up the picture. But... you know... 2D picture and all.
Your line is totally wrong and proves nothing.
