Comming from someone who's seen a lot of dead bodies, you don't look very dead, and the blood is too thin.

When I was in the Air Force, in the Philippines a PAL (Philippines Air Line) plane crashed into a mountain with 320 People aboard. I got volunteered to help collect bodies (no survivors) the bodies of the people who were intact didn't look alive. Their color was very wrong, if you had been sprayed with a thin pale green (almost white) color the image would be more convincing.

Dead people smell like a garbage dumpster on a warm day, but something about knowing it's dead bodies makes it more revolting.
