shading simple objects

I'm just a beginner so I'm not going to say much, except that this is a standard example of shading 2D flat shapes to give 3D effects. Learning this helped me a lot.

If you know how to shade simple shapes, then you know how to shade anything, no matter how complex. Because everything reduces back to these shapes. A human body is no more than cylinders and spheres. Cars and clothes are cones. Explosions and clouds are spheres.Waves are pyramids. Buildings are boxes.

Hope this helps anyone intimidated by coloring and shading complex lineart, because it really is that simple!

Now go out and shade your masterpiece!
