I finally finished my Halloween story tonight

Truthfully, it's disturbingly gory. So much so that I couldn't continue it until now. If it took me over two months to be able to handle one image, I'm not sure about subjecting the unwary to it. How should I tag something like this, maybe a warning at the beginning and a spacer after that or should I just hold on to it. It shares the first several paragraphs with the lynching tree to let you see where the gore is coming from.
