Like them, I admire the artworks of the artist (wearing brown jacket, blue bonnet). I have passed more than a couple of times looking for the right opportunity to click my camera. He seems against people photographing his works, I had simply clicked the camera while it was on top of my son's stroller. We passed by in a breeze and was I glad I did caught them actually - in frame.
This man draws portraits-on-the-spot...if customers do not carry a photo with them, they sit (notice the partly shown white chair) and pose for the artist, in the middle of the plaza!
I remember from a conversation with the artist that he said he comes from Vietnam.
