At my Crealde Urban Sketching course I always have the students do a series of thumbnail sketches so they can explore compositional possibilities before committing to a full page sketch. I do fast and car free sketches along with them to show them each stage of my process.
This was also a lesson in perspective. Anything man made is usually square and knowing where a vanishing point is helps to find the right angles in a cue shapes object. You can see I even drew lines in the grass hinting at where the vanishing point is across the lake.
In the fall the temperatures are just right for sketching outdoors. Fall classes start October 23, 2022.
