The technique of pencil drawing many start, but few specialize. If you do well and work on it the results can be quite impressive.

TIPS:

First it is essential that you draw every day, even if it is 5 minutes or small drawings. Practicing on a daily basis will give more ease to your strokes, and will help you to measure the force to apply in the strokes.

Second, evaluate your bugs, most failures when we start to draw are in proportion, to better observe failures, you can see your picture reflected in a mirror or from other positions.

Third, try to take with you a notebook and pencil whenever you can and at times you do not do anything, draw the first thing you see. This will make you exert multiple drawings of different topics.

Fourth, avoid using other instruments, such as rules or compass, try to do all the drawing freehand. Although it is more complicated, the result will be more natural and realistic.
