I saw this yesterday while browsing brickshelf and loved it all - bookmarked and saved several pics to my hard drive. I didn't notice that you were the builder for some reason.
My favorite part is the skeletons with their supply of LEGO heads to eat brains from!
But the MOC is just FULL of action and events that are quite cool/ghastly. I like how you did the blood as well - I've never seen blood done that way, but I think that it looks quite realistic.
I also like the dirt around the grave and the way that you made it look quite realistic.
One thing I was wondering about - what's with the girl taking a bath?! That's doesn't seem so scary.
