The throwdown is the moment at the end of every sketch walk when everyone places their sketchbooks on the ground or a surface and the group gathers to look at each other's work.It is informal, generous, and one of the best parts of sketching together. You see how the same location produced completely different responses in different hands — the same street, seen through a dozen different eyes.There is no judging, no ranking, no pressure. It is simply a shared moment of looking and appreciating.
