"As part of my (illustration) process, I source and screenshot or drag images of people, places, and things from Google (usually stock photos) which I then combine and trace to create my illustrations. It would be hard for any of these stock photos to be identified outright in my work, as they are mainly used as the skeleton for postures and environments in my drawings. They are transformed by my invention of things like clothes and other details, and by my linework 'style.' What do you think of this? Am I doing anything legally risky?"
