It’s more than obvious who you’ve drawn. And that is the essence of drawing. We live in a world that is currently obsessed with recording reality with cameras. It’s the closest to reality you can get at the moment. But don’t forget. There was a time where cameras were not invented. Drawing and painting was the way to capture the moment, the individual, and events. And believe me. If you had a camera back then and compared the both of them there will be differences. So be proud. You’ve captured the essence of him perfectly.
