18x24 watercolor paper, technical pen and probably pastel pencil or just regular pencil blended with a q-tip. This was done for a friend who owned a wine and spirits shop, so I guess it's a vine. Or a tree. Whichever....
Another half-assed attempt at doing SOMETHING "underground- like". Meh. Magic marker on sketchbook paper. (I still like the name, though.) Late 70's...
I drew these guys with a Pilot Custom 823 FA and Platinum Carbon Black ink. The FA nib has a good drawing width on watercolor paper - one of my favorites. It's a soft nib but I don't use the line variation, just some nice shock absorption with each downstroke. The Carbon Black ink is out-of-this-world good, though being pigmented I fear keeping it in too many pens.
New one shadowed & ready for color. Drawn with a Pilot Custom 823 FA (favorite pen at the moment) with Noodlers 41 Brown on Strathmore Mixed Media paper.
