I am surprised no one has comment on this yet, I love this shot. My guess is that you added diffuse glow in pshop (or similar). I think it works well here, it definately gives the house the 'haunted' feeling. Its almost like infrared film in colour.
Kewl....... A little busy with the trees but what else can you expect with an abanded house. The fence is working here very well. I dig the colors and whatever effect you have going on there. I would have had a B&W hayday if I had come accross this place.
Great photo! Love the composition with that big tree on the left and that fence in the bottom foreground, works great. The filter you added sure does make it appear spooky Nice work!
