Looks like the buildings are quite old. But still the wooden windows look very strong and solid.
Your below concept is interesting.
I guessed that Picasso tried to draw the essence of the image beyond skills. Perhaps, that’s why his paintings looked like a painting drawn by a child.
Those windows were made strong! I hope they last long. I don't know much about Picasso, but I see some similarities between Picasso's painting and Panjeon's calligraphy.
