I can't do overpaints at work because I've no connection to my server, and at home I'm more busy than here with REAL work (hehe, hope my boss never reads that...)

I'm at work now, so no overpaints.
But when it comes to lighting you have to focus your mind, almost in the same way as when your playing billiards. (sp?) Or pool, or whatever it's called.

The little fotons are pool balls, you with the pool cue represent the lightsource, and the sides of the table would be the surface of whatever your trying to shade. But you start backwards, like a 3d raytracing program - start at a particular spot on the surface and try to see it from above - what angle is it facing? What angle is the incoming light? Remember whatever angle it has coming in, that's the angle it will have going out, except to the opposite side of the normal (the normal is the direction 90 degrees to the tangent of that spot). Just like a ball bouncing on something flat. It's all about angles. This means you have to have a clear idea of where your light is of course. At first simplify this exercise by using a single small light, it's easier that way. Start on simple things like spheres and cubes and cones, practise until it's second nature.
