Deck from the Sketchnotes-SF meetup in April at Neo [http://neo.com/]. We practiced people, scenarios and faces. We started with a quick warm-up, then jumped into rapid practice, sketching from word prompts and photo prompts. We shared work at a collaborative critique and learned a lot from each other. The evening wrapped up with links to resources to explore.
