Sometimes, I like to go right to ink. All of these sketches were just thrown down on the paper with little regard to outcome. I love the scratchy feel of pen on paper. Usually, I draw pencil outlines, but not with theses. It helps build control, comfort, confidence and skill.
A few of the weapons towards the end have pencil marks, to show the comparison. The symbol of Sol Invictus was penciled quickly and those flaws showed right up in ink.
