Sorry for the low light pictures, my daylight lamp will ruin the sketch because of the graphite. It reflects too much, and I am just too lazy to scan at the moment 😉
I am working on some speedsketches of Robocop and Full Metal Jacket, just to get the essence for my next cartoon. Every three weeks I draw two cartoons for my team, which consists of two scrum teams.
It is fun to just sketch, sketch, sketch and not erase. Just like with ink, a 6B graphite pen is so dense it will only smudge the paper so you have to live with the mistakes or draw around them.
These sketches give me the essence, some feeling for shading and value. It is something to mindfully do, for example in the a waiting room of a hospital.
