Luc posed remotely for this drawing, which was produced using two Bic Biros. The yellow Biro is used for highlights and is set down first. The blue Biro is for shadows, and it’s this one, which draws second, that brings out the image.
This kind of image is designed to be viewed from a distance so the details fully resolve.
Each of the single lines that comprise the image start in the top left corner of the page and finish in the bottom right corner.
