Don't you think that his arm ought to be much farther inside the meatgrinder to 'produce' the amount of meat displayed? Furthermore what's up with his bones? I don't think grinding his hand an arm would give you such declicate minced meat. Anyway, somehow the scene, though definitely gruesome, doesn't manage to really touch me. Thus I don't feel the horror one would expect. And I think it has something to do with the way you depicted the scene: contrasting the mutilation with a supposed to be entertaining ad. Somehow it doesn't work ... for me.
This is amazing with all the details and the facial expressions! Can you please make a version with a naked little boy, going down a huge meat grinder feet first, while another naked little boy stands next to the grinder, holding his hand and looking in his eyes? I would so much love to see that!
