No Blood!

But I would play with the lighting and texture.

One possibility could be to use either some slight desaturation as in just muting everything a few percent or even trying some gradient work where the color fades one way or the other across the sight line.

The three part split injects all kinds of interesting connotations thematically and psychologically to the photographs context. whether the obvious of the saw cutting or the tryptych philosophy of components of the story, this is a subtle piece of dark humour combined with the titling.

Another 'trick' would be to distort or simply rotate one of the three elements in it 'frame' to accentuate the 'cut'.

Very, very creative thought process behind this presentation. As usual, looking forward to more. But no Blood!!
