These are some quick sketches I did, no pencil drawing underneath, just starting with a thin Micron and then using bigger pens and brush pens. A few I toned using Copic grey markers.
These are more quick ink sketches, the top 2 are toned pencil drawings made using 4B lead and a blending stump, then erasing with the Tuff Stuff eraser.
2 small panel drawings. The ninja one was a lot of fun trying to imply the sea below.
Very loose brush pen sketches and a toned samurai guy.
