The title hints at a dark past, and now the image seems spookier. The wrought iron fence is a good touch, a measure of attempted safety. Now the peaked roof starts to resemble a witch's hat. The processing furthers the mood. Well realized.
Or is she still there? The drape of that curtain suggests someone behind - watching. Creepy.
Your choice of waning/waxing daylight certainly lends to the spooky mood, and shooting the fence in the foreground suggests perhaps something is being contained behind? Probably the most eerie submission in this challenge.
