Experimenting with Watercolor Pencils / Illustration, Traditional / By Michael Wanting to add some color to my traditional drawings, I dug out my old Staedtler watercolor pencils I’ve had since I was a kid. I drew this beetle from photo reference on watercolor paper. I did the inking using my trusty Kuretake Bimoji brush pens. Their carbon ink is not only very black, but also totally waterproof. If you like the beetle, why not check out its store page.
