I've been trying out sketches with biro.
These quick, rough scribbles in my journal really don't take that long. When I start they always look dreadful, especially when I begin the shading around the eyes. But as I keep going, they start to come together, and by the end I usually like what I've done.
I tried adding colour to this one. I think I prefer my biro sketches without colour, but I want to experiment more.
