Leaf, freshwater snail shell, starfish, hermit crab shell and sea urchin shell done in a variety of media: graphite pencil, watercolor pencil, ballpoint pen, fine-liner, brush pen and watercolor. Done on A3 paper.
All are done directly (without pencil sketch) and very quickly so they look.. like they do.
