I've done this work using 7 pictures taken with a Canon EOS 5D Mark II.
The pictures have been taken in a dark room with a flash, facing the left white wall.
Picture of me with open mouth.
Skin turns blue, mouth is enlarged and neck's veins come out.
Tongues are added.
Are added hair and wrinkles of cheeks, nose and forehead.
Moles are removed, reflections and shadows are accentuated and the face characteristics are improved with the Liquify.
