sketch of a skull
Here's a sketch of a skull I did with ball point pen. I am not very good at drawing from nothing so I had to look at a sketch of another skull to draw this. I am still not very good so comment away.
mmm the chin looks a bit too big. overall it looks pretty good.
i realy like the shading you did here. it gives the head a real sollid structure.
This well but if you want something but real you guide yourself looking at some skull for internet. It would be brilliant if you changed the pencil that you used for a pencil it mines I brandish and you use a difuminador (one doesn't eat the they call in English, but it is a tube of good-looking paper to a pencil, I believe that that effect tells him smudge) to give the shade effects.
(My English excuses, but it is that I help myself with a translator)
