My main day-to-day sketching activity, in a watercolor sketchbook. I mainly use a small watercolor kit, a fountain pen, and/or a ballpen.

For a 100-day project, I varied my urban sketching a bit: The task was to add some fictional element to whatever I found in the city. These are a few of my favorite sketches. They have all been inspired by places in Munich – can you find out which?
