I wanted to create this hell bent creature like you see on all the RPG computer game covers. So i started it and this creature ended up looking like a dragon. 

He was drawn using Pacer mark .02 .
I originally started off with a sketch of his skeleton just to work out how he would look. The skeleton helps determine majority of the facial features and this method works on most creatures with a skull. I then sketched out what he looks like on the outside. So he is a four eyed, fire breathing dragon with horns similar to that of a mountain goat.
I tried to draw him roaring, but he still looks somewhat menacing.  I shaded him in with the Pacer mark .02 as well. I was going to draw his entire face but i also wanted to shade some bone (i haven't done that in years). So i decided i would do a cross- section so that i knew how to draw him later on.
I drew him last weekend

Enjoy!
