Click Image to see larger version in my gallery 4 x 8 in - 10 x 20 cm. Another quick line drawing. It always surprises me how effective the result can be for such a comparatively small effort when working in this line and wash style (and this is not a good example).
I used an old 'Rotring' pen for this one it, was harder than expected to control the direction. I will have to stick to fibre tips in future.
This is roughly what I was seeing.
