That deer is clearly shot in the "void"[8D]I don't know, whether it's in the guts or not or whether it will live or not or whther I would have shot or not with the buck walking around seemingly heathly. I will say that I can't imagine how the exit could have been that low and the arrow not hit some guts. Also, it appears from the exit that it almost certainly had to go under the spine, though from the entrance it appears possible to have gone over the spine.
