You can see on the right, all my layers that I used to create the zombie effect. There were some that I couldn't get in the picture without scrolling, but you get the gist of it. I used the effect of scars, and blood, skin texture from cracks in the pavement (I used it on my face, on my hands, and on my feet), white eyes, guts in my hand, zombie teeth, and a reflection in the water.
