To start off, draw a rough rectangle on a piece of paper.
Step 1: How to Draw a Skull
This instructable well show you how to draw a skull.
Devide the recrectangle into rough quarters
Devide the bottom half into thirds
Draw on the eyes as two large circles halfway the top and the bottom.
To draw the other major facial features, draw a tingle between the two lines in the middle the skull and then draw a slight curve between the other lines you drew in the last step.
The teeth are always bigger than you think but just draw about eight on either sideof the curved line.
Next, draw the jaw. To do this, draw down a bit from the last third then curve it inwards so it meets the bottom of rectangle.
Then you have to draw the top of the head. Make sure it goes to the very top of the rectangle and give the skull some cheek bones by curving outward a bit.
The shape of the skull is now finished. Start sharing in the dark darkest areas in the eyes and the noise. I have used cross hatching with a pen buy you could do it any other way.
Finally, add some more detail with shading and then get rid of the unwanted lines.
