I like the color, contrast, slight grain and light/shadow mix. It would be great to have a black cat in the foreground.
I'm having trouble with the composition. It is slightly crooked, and I am inclined to suggest going for a much more crooked angle for a "spooky" shot.
I am also distracted by the bracing in the upper part of the structure. It looks out of place somehow, like new lumber attached to an old structure to reinforce it? Maybe that is just the way the light hits it or something.
Could you get a shot with the shadows coming towards the camera? That might be cool too.
