This is also graphics, but not computer graphics.
I like the small details in the drawings. I use a mechanical graphite pencil and matches (ordinary matches, several pieces sharpened at different angles. My own drawing technique) and I often have to make the 0.5mm pencil lead even thinner to draw the details as I would like. The original drawings on paper are small in size and therefore usually make the better impression.
Tools: graphite pencil, paper, matches.
