The author of the tutorial, Laval Yan, used AliveColors 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: Effects -> Built-in Plugins -> LightShop.
In the AKVIS presets list there is 073.xml that suits well for our task.
Then smooth its edges with any appropriate tool. In AliveColors you can use the Smudge tool :
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!
