Indeed. Most of the drawings I share on here are either on 5.5" x 4.25" cardstock or 8.5" x 5.5" cardstock. Any larger, and coloring them in would take forever. These here, I was intentionally drawing small. I was trying to make with pencil, the type of lines a person makes on metal using hammer and chisel (like what you find on gun and coin engravings, for example). So the thicker dark lines represent deeper and wider grooves while the thinner light lines represent shallower and narrower grooves. If you click the picture and look at it in a 1:1 pixel ratio, you can really see how the darker lines are really dug into the paper. It was an experiment, and a fun one at that. I intend to do more down the road, see how small and detailed I can get.
