This is the cover of my home-made sketchbook. A corner of the street where I live. I did it with felt tips, several shades of green and brown. It's a bit wonky but I like it that way. There are places where I've tested new colours and decided they didn't work out and then left them - notably the green and black windows and the bit of blue and turqoise paving stones. I think it adds charm. Mistakes are good.
