Let's not delay things any longer! Here is the PSD File ;)
As usual, with all the stuff in its own layer so you can have a fun time playing around with the colors, the tones, the saturation, hue... Have a nice time, be creative! Do you think that the shading should be darker, or lighter? Change it! Do you want to remove the glowing effect of the eye? Go ahead! Make your own piece ;D
Don't forget the secret code:
