You are searching for opinions evidently by your question if it was a
bad shot. But by the responses I have read that you have posted you
actually were not looking for honest opinions from your fellow hunters.
You were fishing for compliments because "you" thought this was an
awesome shot. If this was not a doctored photo then thank goodness
the deer is down. Too many things can go wrong with aiming for a head shot and in my opinion you got lucky this time. Just a little left or right, up or down, and you would have an injured animal. Do the right thing next time and take them where you know the best shot is. If I was in need of the meat to feed my family, I would have to take a higher percentage shot to ensure the harvest. So my opinion of the shot would be, yes you made a good shot..........but.......you made a poor choice in "shot selection."
