The author of the tutorial, Laval Yan, used Adobe Photoshop and two AKVIS plug-ins to convert a photo of his nephew into a photo of an alien.
You can make/edit the selection in AKVIS Decorator.
Open Texture Library with a left double-click on the texture pattern; in the Animals group select the texture with fish scale.
Adjust the parameters Brightness and Warping (others can stay the same) and press the button .
Select the hair of the boy with any selection tool and call AKVIS LightShop.
In the AKVIS presets list there is Sample 03 that suits well for our task. Select this preset from the list and press the button Edit to open the Settings of this preset.
The preset has only one element - Particles. First we will change the color of the element: on the gradient line we will set black color for both yellow and violet sliders.
Increase the size of particles (Particle Size) from 25 to 45%. Change the value of the parameter Scale X of the Scale modifier to 140%. Press the button .
Now add to the alien's haircut some locks for a natural look. For this purpose create a transparent layer, call AKVIS Lightshop again and repeat the previous steps.
Apply one of AKVIS Lightshop's presets to create the effect of "snake eyes". Adjust the parameters so that the stripe was in the center of the pupil, as it is shown on the picture.
Apply the result by pressing the button . Use Blur tool and History Brush to correct the edges.
Repeat the same for the left eye.
Here is our alien!
