Hehe - I took the picture of me and then digitally added to it as well. Basically when I do work like this I start out with a photo and get as much into the original photo as possible before taking it into PS- makes it much more realistic that way. On this one I used real blood (cows blood from a butcher), dirt on my face, and a clear gel face mask that peels off like skin when it dries. After I take the picture I bring it into PS to "decay" it even more. A lot of dodging and burning, color adjustment, and sometimes a brush or two.
