Shading a Sphere

I recently watched a video on shading, and now I am really impressed with my sphere.
I am using a Hb pencil, but you can use almost any other pencil!

First I drew a sphere, you can use a round object if you can't do a good circle. I did it without, so it is possible!
Try to make it as light as possible.

Then figure out where the light is going to be.

Then divide the ball into two sections. one side will be dark the other side will be lighter.

Make sure to try and shade evenly!
Sorry about the terrible pictures.
