I thought the biggest challenge would be that I can't take photos, but it's not, it's the heat, 38 degrees and the shadows move fast. I noticed the interesting stuff going on either side, whilst drawing -you can't see it. Perhaps I do several drawings at once and have a sketchbook for 'snapshots'? I do think it's nice to know there's life just outside the frame.
The Flatbread man, just out of the picture.
