The green wall looked vacant.  As I was looking for other structures to add, I found two choices nearby; a parking meter or a street lamp.  As I drew the parking meter corresponding to its life size, it looked insignificant.  I decided to double the size of the parking meter and made it as tall as the wall.  Additionally, I borrowed interesting pipes from the next building and I changed the dark brown ladder into lighter green to introduce more contrast to the green wall.  At the end of the day, I was satisfied with the painting and also amazed that it took me a whole day to think and to make these choices.
