In the beginning there was a traditional sketch inked with a staedtler pigment liner. While I was watching a course about lineart done with Inkscape over at Skillshare I had the idea of using the scanned ink sketch for doing a lineart drawing in Inkscape. I hadn't used Inkscape for quite some time so it took me some time to refresh my knowledge of this software.
I then saved two versions of the drawing - one as a lineart drawing and the other one you can see here.
