Hello every one,
i will give you at the first some explanations about the true cell shading and fake one,

go to Edit Mode by press Tab key then press A to select all, and press right click on any outline in the 3d view and click on Split Area the press on grid icon (3d view icon) and choose UV/Image Editor.
Press on Image Button and click on New then make the size 1 width, 1 height and color black.
Click on Mesh button > Normals > Flip.
press the ` button (beside the button 1) to make all the frames appear, and click on Num3 to make the view on side view, then press Z then Z again if you are in the texture mode, if you are in solid mode press only one Z.
