Step 1: Gather Your Source Photos
My friend's beautiful daughter was gracious enough to pose for me, before heading out on a hot date. You may notice there aren't any shadows in her photo. We live in Washington State, where the sun rarely shines this time of year. Only a few hours drive from Forks, where we all know the sexiest vampires come from.
Step 2: Prepare the Background
A nice blue tint helps make the scene look a little more depressing. Create a new layer and set the blending mode (top left on the layers palette) to color, and the opacity to about 20%. Select the paint bucket tool and fill the layer with a nice blue color. You can then play with the fill color and opacity. I was going for sort of a moonlight effect.
Next add some blood and decay. I found a peeling paint texture to cover the wall, and placed that on a new layer, and set the blend mode to soft light, and the opacity to 65%. Hit Cmd + T (Cntrl + T on a PC) to active the free transform tool. If you hold Shift + Cmd you can drag the corners of the layer independently to adjust the perspective of the texture image.
For the blood, go online and search for Photoshop Blood Splatter brushes. There are tons of free brushes to choose from. Download the ones you like and load them into your brush palette. Experiment with your new brushes, with the color set to various shades of red. When adding blood i use a multi-layer approach always building up to the look I like. Don't try to do too much on any given layer. Play with the blend modes (overlay and hard light work well for this) and opacity of each layer. Keep in mind blood darkens as it dries, so added a little bit of darker blood to help add some bloody history to the image.
Step 3: Prepare the Body!
Create a selection of your model. If your just staring out in Photoshop, the lasso tool is a good place to start. Or if you are a little more experienced, and your model has lots of stray hairs, and you want your final image to look as real as possible, the magic selection tool (in CS5 and newer) works well coupled with Refine Edges under the Select menu. I'd suggest going online and running through a tutorial or two first. But, I recommend using the good old pen tool. It's easy to learn, and you can make a precise selection and easily adjust it as you go. And since were creating a vampire image, the darkness of the scene and all the blood and gore were going to add will help hide any rough edges.
Copy and past your vampire onto a new layer on your background image, and scale it to fit into the scene. For reference I named this layer "Model".
Step 4: It's All About the Eyes
Create another layer on top and create circle selection over the eye and use the gradient tool, set to radial gradient, from gray to black. Scale it down till you get the desired highlight for the eye. Drag this layer behind the Model Layer and place it within the eye opening on whichever side your light source is coming from. Duplicate the layer and move to the other eye.
Step 5: Pretty Up the Mouth
Deselect the layer mask by clicking the first thumbnail on the Fangs layer in the palette. Use use the brush tool with a low opacity to paint some shadow on the top of the fangs so they look more like they're under the upper lip.
Step 6: More Blood Please!
Finally, some finishing touches. The door opening in the background was screaming for something. I did a quick trace of a man with his arm slightly out, colored it black, scaled it down, put a stake in his hand and gave him a shadow. I also added some restraints to compliment the mental hospital environment.
