And that illustrates what is probably a common difference between photography and painting: would anyone makiing a painting cut a body like that and place it where you did?
To me, it shows that your artist is actually non-identical twins.
As a photographer, it is both accepted behaviour and highly effective. As a painter, would you ever think of intentionally framing like that? You are a good person to ask, being pretty damned good at both disciplines.
