Turn Angelina Jolie into an alien - part 1

You can usually find fairly large images using GoogleImage Search, hi rez setting. You should choose the largest photo you can find, we will need to keep some portions large while shrinking the others. Your final result will be smaller than the original image, keep that in mind.

Open your image in photoshop and name the layer "FaceBackground." Make a copy of the layer for safe keeping and hide it. Do a quick and dirty selection around the facial area and put it on a new layer. Name this layer "BigFace." Make this layer 50% opacity for now. Go to FaceBackground layer and shrink it until one of the eyeballs fits like a giant one on her forehead. *See pic.

Turn BigFace layer back to 100% and make a copy of it for safe keeping and hide the copy.

Stay on BigFace layer and copy each eyeball to their own layers. Use the outer halves of each eyeball to form the large one for the forehead. Erase any of the remaining picture. In most cases, it is sufficient to just use a regular feathered eraser around the eye for blending it into the forehead. Use any natural wrinkles or skin folds that come with the eye, it looks more authentic.

Merge the eye layers into one and name it "BigEye."

Do the same thing with the lips, put them on their own layer (name it BigMouth) and position over face and erase extra stuff. You can use Filter/Liquify to distort or make any adjustments to the mouth or eyes.

Keep in mind what you want to do with the nose. If you want to give your alien a huge honker, then you might want the mouth tiny. Think about the entire design while you're making all these adjustments along the way.

I've decided my alien won't have a nose at all. So I made the mouth HUGE!

Time for the ear. I think a little point on the tip is all she needs. You may do more if you like. Go to FaceBackground layer and use the square marquee to select an area around the ear, copy to new layer, name it Ear. Go to Filter/Liquify and play around until you have something you like.

TIP: Make the tiniest increments of change as possible. It takes longer but the image will stay sharper. If you take a huge brush and make a major stroke, it will become very blurry. Remember, you can always undo!

When done distorting, erase any extra stuff from around the ear and merge down into FaceBackground.
