This was my first attempt at line art, line art is "usually single-color drawing (such as one made with a pen or pencil) with little or no solid areas, and no shading effect other than cross-hatching."

I did all of this with the pen tool, Adobe Photoshop. I would say it's about 85-90% done, it's still lacking in some detail. It will be finished one day.
Note, I did not do the drawing.
