With this piece, I first drew an elderly woman in pencil on paper.
I then scanned it into a USB with a printer, converted it to a bitmap with the drawing software Inkscape, and then proceeded to draw on it digitally with Autodesk Sketchbook (the not-pro version, because I'm too cheap to want to pay for the pro version).
And thus! This is the final product! I hope you like the way I combined the two styles of drawing... literally!
