Look at a picture of a skull, get a feeling for how it looks.
Take a pencil and lightly draw a circle.
If you wish to draw the skull facing you, make a horizontal line and a vertical line that go through the circle, then draw two vertical lines on the left and right side of the skull. (See illustration for further reference)
Make an angled "U" shape at the bottom, closing in the chin.
Two large circles near the middle of the circle will represent eye sockets, as well as a triangle for the nose.
Draw lines for the mouth, and then teeth. These can be rearranged depending on how your person will look.
Erase excess lines, and darken your drawing.
Use a shading pencil to shade in the eye sockets and nose.
Practice! Try using shading once you get good at this.

Draw lightly for the start once you've got it make it darker.
Practice, and then practice more! Although it might be an overused phrase, it's true, "Practice makes perfect!"
Don't be afraid to trace. Tracing helps you to get the feel for the drawing.
Try drawing the skull at different angles. This will help greatly.
Do your best, even though when you show it to other people and they laugh. Keep practicing!
