can you post the full shader here? Maybe you have some hints for the graveyard? - how would you animate it for best visual effect? - could you perturb the result?
Just for the case a skelleton walks around through this scenery it would be nice to see an effect to the fog. Ok, I really have a very dark scene in my current project. Some nice fog like yours could improve the mood.
