You need to add something behind the fence; A landscape, moon or something (maybe an old village on top of a hill). Allso a little fog would look nice. The ground looks a little bland. Add some more detail there (dead grass, bones, candles..etc). But just add a full moon there first, in the background. I know it's very cliche, but it will work non the less. You need to make it look more dramatic. Fog and full moon allways work. ;)

 Tilt the camera slightly. Colour some of the lights blue. Things like that.
