Photoshop - Vampire

I copy and pasted the bottom image into Photoshop to begin with, then by opening the tool pallet I selected the sponge tool. Secondly, I changed the mode to desaturate, changed the flow to 75% and changed the size of the brush to an appropriate size. Then I began to colour in all of the face in a dull grey shade (avoiding the eyes and lips) to give a good "vampire"effect. I also used this around (and on) the eyes to make them darker/black.

For the lips, I used the burn tool. I made sure the range was turned on and the exposure was 50%. I then painted over the lips to create a vivid bold red colour. I also changed the exposure at times to create different shadows and shades.

I zoomed in on the teeth then used the magnetic lassoo tool to outline the selected tooth. I right clicked layer via copy then edit, transform and warp. I then pulled the tooth into a "vampire fang" shape and applied this to both teeth at both sides of the mouth.
