They way the light falls makes objects look 3 dimensional. Shading helps to show the difference between lighter and darker areas of an object thus makes it look real.
Shading should be though through. From where does the light fall? Which side is going to be the darkest and the lightest. Logic is critical for shading otherwise the drawing will look unrealistic.
Start by drawing a circle. A sphere is just a three dimensional circle, so once you have your outline you will need to determine the direction your light is coming from. Having established your light, remember the area furthest away from the light will be in deepest shadow, so shade in that edge. As you move toward the light the shading will need to get lighter. There should be a small area (round in shape) where the high-light is and this should be white or untouched. Finally using the light source, put in a cast shadow to make your sphere look like it is sitting on a surface.
As many as you think it should have.
Having the skills need to make impressive three dimensional drawings takes a lot of practice. In order to have different views of the object you are drawing, you should draw the top, side and front of the object.
HB pencils are versatile and ideal for drawing because they offer a balanced hardness that allows for both fine lines and shading. The medium graphite composition produces a good contrast without being too dark or too light, making it suitable for sketching and detailed work. Additionally, HB pencils are widely available and easy to erase, making them perfect for both beginners and experienced artists who want to refine their techniques.
So the drawing is a very fine line and easy to rub out?
Clear and dimensional accuracy in marking out is critical in all circumstances. You spend the time marking something out then you or others should be able to see it clearly. Drawing requirements must be followed at all times you mark out to the tolerance the drawing states.
All should be avoided except talking.

drawing is a skill as well as talent, i have been drawing as a child, and now i am payed to draw... i have never attended a drawing class, but practice makes perfect. i suggest you go on tutorials that teach you basic shading and sketch, when you get the basics right, the rest is practice. to see some good art: www.photobucket.com and type in anime or anything you want to draw
