i started with the graveyard. for the second layer, i pasted down the traintracks and then set transparency on the tracks at 50%. for the 3rd layer i took an image i'd shot of some fairly thick storm clouds, then set transparency at fairly low, so it was misty then for the last layer i took a copy of the graveyard, cut out just the few tombstones that were at the end of the tracks and pasted them dow so they show up while everything else fades away. then i merged the layers. Thanks for the compliment :)
