This morning I went out and took pictures from the street for reference. I felt a bit silly taking pictures of, well, nothing. And people were walking (which is super helpful for reference but makes it even more embarrassing). I got one where someone is walking with his head turned and looking right to the camera. But being able to do this is one of the reasons I’m happy I set the comic in Athens
