As per my usual style, I was going for a lot more of the smaller details as opposed to the bigger picture.
I felt oddly uncomfortable while I was there, far more than the previous visit. Found myself constantly looking over my shoulder, feeling as if I was being observed. This time I didn't venture into the darker parts of the building, and left quite quickly when the feeling just became too strong.
The door had been newly boarded up since my previous visit, and newly opened by somebody else, so they are obviously keeping an eye on the place.
This initially gave me a horrible shock when I first glimpsed it, I thought it looked like a hideously deformed skeletal foot - shows where my mind was going at the time.
