Those are very lovely trinkets. But they are not representative of the nature of crucifixion. Christ did not die in a beautiful, peaceful way. There was blood and stench and suffering and unbearable pain. None of the crosses you posted show any of that, because it is offensive to people to see that kind of suffering.
The only thing I would change about the chocolate sculpture is, I would make the face broken to represent the beatings and the suffering he took for us. He had been torn apart by the scourging. He would have been filthy from falling bloodied onto the dirty street. He would have been covered in welts and sweat.
Over the centuries, artists have cleaned Christ up and given him a countenance of slumbering, but he really died in agony.
This is more like he would have looked on the cross:
But even that image has cleaned away the blood, sweat dirt and tears. All those hideous renderings of the crucifixion in old gothic cathedrals are more accurate than anything we hang in our churches today.
