Here is a demo done in what we call our Long Head Drawing class. Done in graphite, these drawings are good for taking the time look for the subtlety in form. We use a smooth velum bristol paper and various grades of graphite. I like to also use a mechanical pencil.
Here is a second preview for a piece that will be available at the IlluXCon this November. This was done for Sony Online Entertainment's - Legends of Norrath card game.
