Here is the progression of Elvis the goat in graphite pencils; 4H {warm tone}, 4B {cool tone} and a HB Neutral tone. Notice how I only have an outline sketched and not set in stone. When you have trouble sketching a form out start with one shape such as an eye. Work from one eye out, therefore allowing it to be easy to erase an outside form lines. If you try to draw the outside lines first and then go back and “TRY TO FIT” in the eyes in later in an open space it will not work unless you have Mastered drawing and realism drawing. Work from one form such as an eye and work from the eye and outward.

Use the warm and cool tones of the graphite to set form in space; remember warms tones will come forward and cool tones will go back in space to help create form and shape. Without the darks there is no realism.

In the following picture this is how far I was able to get in two hours.

I can not stress enough if you are an over-sketcher on cheap paper of 140lbs. or less you are wasting value sketches turned into a drawing on CHEAP paper. You are not doing yourself any favors by doing this. Get yourself a really good drawing paper pad of 140lb or better. Even buy Illustration hot press drawing board this way when your over-sketched  doodle is over-sketched it can become a serious composition because it is on good acid free paper or board. Use the cheaper drawing pads of 140lb. or less for Doodles or thumb-nail sketches. You have better results from the graphite on better paper too. Cheap papers are not made to hold serious artwork.
