Planning New Painting

I am starting the crucifixion painting at Artists of Grace. I like the head I sketched but the canvass is not large enough for the size of that head. I am thinking about having the arms stretch off the canvass. One of the other artists had just the hand as a sculpture extending out from the cross, but she could not hang it because it was too powerful for children to view. It could be all good that the hands are left off. I want to emphasize the Christ was still God even through all the pain so emphasize the face and eyes with power and have the rest of the body with torn up palette knife strokes. Maybe it will be strong enough, but not graphic enough to scare children.
