TUTORIAL & MAKING OF LINK

“Collar of magic pearls” arrives after a global look on my work, felt that my theme turn too muh to "toonish" rendering pictures and lose some relationship with the technique of the physical laws of reality. ( you know... radiosity / SSS material / shadows/ specular light.... all kind of things 3D artist are used to do, and 2D artist should sometimes learn more ;- ) )
So , I started a test which is quickly muted in a review of my various techniques that was sleeping, as bump, color layers, textures.... in a sharing between Painter and Photoshop. Made between 11h00 of the morning and 20h00 --> I specify it because it is rare that I “eat” all my drawing only on one day.
