This category includes all kinds of pictures which were generated in a relativly short amount of time. From a sketch another picture can be created but a sketch can stand on its own too. Sketches tend to not focus on details but more on bringing the idea from the brain to the paper or screen. They can be more fluid and include more movement. The viewer of the sketch completes the missing details in his own mind.
This Sketch was created on a sunny Sunday afternoon in my garden. I used pencils, fineliner and Copic markers.
