Two versions of drawing the hallway in my house (I only have the one!) in one point perspective for an exercise in Drawing on the Right Side of the Brain. The digital version is traced from a photograph, while the paper one is eyeballed. I did both because of my ongoing struggle with the viewfinder tool. Comparing the two, you can see that I am distorting things a bit in the freehand version.
I never got shading on “pencil” works in Krita to go well, so the digital one is pretty stark. There’s a pretty good lived-in feel to the paper version.
