Facing the blank page of a sketchbook can feel intimidating. I enjoy warming up with small challenges I give myself, especially when my time is limited. Here’s one idea: select a location and do four monochrome value thumbnail sketches. Keep the sketches small (just a few inches across) and focus on big shapes and areas of light and dark. Set a timer and spend no more than 5 minutes on each sketch!
