Really drawing is an interesting activity bit a bit difficult especially drawing human faces in different shapes. It is a time snatching activities and everyone cannot raw faces as they are. It is a technical art given by to special people on earth.

I have been a drawing master since my childhood. There are some basic points to remember in drawing faces as..

Draw an oval slightly wider at the top than bottom
On the middle horizontal line, draw two almond shapes – these are the eyes
Down the center line, draw a nose.
Go back up to the top horizontal line
Add a mouth. Make a flat
Drawing the hair
Finish with the neck
Add a collar or neckline of some sort
Finished.

Follow these five steps you will be able to draw accurately human faces with pencil colored or black. Further keep in mind these points,,

Keep in mind the expression of the person for whom you are sketching.
Don’t give up, but accept criticism. It will make you better.
Sketch lightly on the first outline.
If you don’t get it right, try again. If you end up wanting to rip your paper, take a break to blow off some steam.
Make daily rough sketches of people you see in media or on the streets.
Add different tones and shades to show different parts of the face.
Concentrate on every detail because the smallest ones can make a difference.
Always try to focus on your pencil tip; it should be sharpened. You must draw figures with light hands in order to erase unwanted marks.
As you know the old saying practice makes perfect
Keep in mind the small details like freckles and beauty spots and make sure it looks like the person. You won’t get it right the first time so be careful and don’t press too hard.
