Create for the beginning a new file (File>New) of 1600x1200 px and 72 dpi. Paint it with black color, applying the Paint Bucket Tool (G).
Start representing the face of an alien. Firstly we need to represent the face's contour. Choose the Pen Tool (P) and draw the contours element as in the picture below.
After that, select on the made layer Blending Options>Inner Glow, by making a mouse click on this layer on the layers' palette. Start setting each option like it is shown below.
Blending Options>Bevel and Emboss
Blending Options>Bevel and Emboss>Contour
Blending Options>Satin
Blending Options>Gradient Overlay
On the next table there may be seen the colors' codes of the Gradient Editor.
We need to obtain the face from below.
Using the same Pen Tool (P), try to make the eyes for the alien. In this case it's enough to make just one eye which may be copied later (Ctrl+J). The eye may be also turned, applying the Free Transform selection (Ctrl+T).
Give the same Blending Options - Inner Shadow parameters for both layers.
Blending Options - Outer Glow
Blending Options - Bevel and Emboss
The eyes, as you may see, are finished!
Pass to representing the shadow and the highlight on the alien's face.
Set all the parameters from below for the layer containing the shadow and the highlight.
Blending Options - Inner Glow:
Blending Options - Gradient Overlay
Gradient Editor:
On this stage we must get the next picture.
Create a New layer and put it together with the layer containing the shadow and the highlight, applying Ctrl+E. Marking them preliminary, put together the layers on the layers' palette. Next select the Burn Tool (O) and blur out the edges on those places, marked with red color.
We must get the next result. Create a New layer after that and choose the Brush Tool (B) to insert a spot of white color. After that, choose the Smudge Tool (R) to blur out the spot on its diagonal direction. Finally make the necessary corrections on the picture with the Eraser Tool (E).
Try to make next an ellipse with the Ellipse Tool (U) and situate it under the face's layers.
Set the next demonstrated parameters for the layer: Blending Options - Bevel and Emboss.
Blending Options - Bevel and Emboss - Contour
Insert also a total transparency (Fill 0% for the layer).
Make one more circle, applying the same operation described above.
This is the result we must get on this stage:
Now we have to introduce the necessary text (I used the X-Files font from dafont. ), using the Horizontal Type Tool (T).
Set the text's demands as the next table indicates it.
The parameters for the lowest line:
After that, make a small circle, as for the X letter to be located in it.
Set then the next demonstrated parameters and Fill 0% for the layer.
Blending Options - Stroke:
The X Files wallpaper came to end.
