Here is where you will start sketching in more detailing to the demon skulls head. First sketch out the indents on the sides of the skull head and then add some detailing under the eyes, around the nose, and on the horns. To finish drawing the demonic horns you will draw the vertical lines that go all the way up the skull. Lastly you will sketch out the teeth and then sketch the detailing bone lines under the teeth as you see here. Erase all the guidelines and shapes and then move to the next step.
