To cast the face, start by laying the client back in a chair. Protect their eyebrows and lashes with vaseline and wrap their hair in saran wrap.

Mix alginate and warm water 1:1, pour it slowly over the client's face, using hands to work out any bubbles and making sure it gets into any crevices like the eye cavities. Cover the septum last.

Allow it to set and make sure it's thick enough all the way around. If you need to add more alginate do it now.

Start dipping plaster bandages in water, activating the plaster with your hands, and molding them around the face. Form a perimeter first, then fill it. 

Make sure to cover the septum with at least 4 layers to make sure it stays stable.

Let the plaster set and have the client move their face around until the cast comes off easily.

Plug the nostrils with monster clay and set the cast in a box of packing materials so it's horizontal.

Mix up some hydrocal by sifting it into water by hand until dry lake bed peaks begin to form, then hand mix it together. Pour into the mold, tapping out any bubbles.

Let the mold set and then demold it.

Paint the face cast with sealing wax to seal the plaster. We did at least 2 coats to make sure it's thick enough.

Use monster clay to sculpt your prosthetic onto the face. For my snake, I used my hands and a silicone tool to make the smooth shape of the snake, and then a metal clay tool to add the texture of the scales. Make sure the clay is smoothed to the edge of the face so plaster doesn't get stuck underneath.

Cover everything in vaseline so the new plaster doesn't stick to itself.

Find a bucket or tub that fits your face and mold with at least an inch on either side so the relief isn't too thin.

Create a clay slab for the bottom of the tub so plaster doesn't get underneath the face mold. make sure the face mold is embedded into the clay with no cracks.

Create a wall with the clay around where your sculpt ends. Don't cast the whole face if you don't have to. I ended up making my wall just below the lips.

Mix up more hydrocal, pouring it in until it covers the entire sculpt. Let it set.

Once it sets, remove the cast from the tub and separate the face cast from the new relief cast.

Pick all the monster clay out from the relief.

Mix a 1:1 ratio of dragon skin, mixing any of your pigments into part A. After the two parts are mixed, add silicone thickener to ensure your silicone isn't too runny.

pour the silicone into the relief, only using enough to create a thin skin around the entire mold. Let set.

Mix up some soama foama, this time in a 2:1 ratio. If you want to color this as well, also mix your pigment into part a. 

Depending on how vertical your mold is, you may have to do several rounds of the silicone foam. Pour it into the mold, put the face mold back in place so the foam sets in the shape of your face. Put weight on the mold until the foam sets so it doesn't expand too much and push the face mold out of place.

Let the silicone set, and then remove it from the mold. Wash with soap and water to remove the vaseline residue.

Paint the prosthetic with alcohol based paint. I used a darker green for shadows, and yellow and gold colors to add highlights.

Before makeup application, style the wig: I used extra-large rollers, pinned them in place, steamed them, and brushed out the curls when I was done to create nice waves.

Put on a wig cap and pin it in place.

Now we get to the makeup! First, I glued down my eyebrows. You know the drill by now- several layers of glue, then set with setting powder.

Coat the back of the prosthetic with derma-tac, a silicone adhesive. Let it dry until it gets tacky, then stick it in place on the face.

Apply primer, foundation, and concealer. (I actually did this before applying the snake, and then took makeup remover and rubbing alcohol to remove the makeup where I wanted the snake to go. Either way works.)

For the eye look, take a metallic olive green eyeshadow and put it around the entire eye and lower lash line. Deepen it with some black and dark green matte shadow in the inner and outer corners, blending it all with a blending brush.

Take a multichrome liquid eyeshadow and an angled liner brush and apply to the center of the eyelid to replicate a snake's pupil.

Apply mascara.

For the lips, use a blood red lipstick first, then a red lip oil after that.

Take stage blood and drip it from the lips. You can also apply it in splotches around your face and down the neck- I liked that the blood on my neck almost looked like a hickey until you got close, which added to the "lust" theme of the look.

Set everything with setting spray.

Put on the wig and you're done!
