When April's theme was announced, all I could keep thinking about was the "openings" of these gates and the negative/positive spaces.
Most of the homes are ornate and have beautiful gardens and you can peek through the openings to see all the elaborate architecture. You are looking at homes that were built in the 1700's and still stand today.
I decided for my sketching experience was to find an interesting alley or home and draw what I saw through the opening. Here is one of my sketches....
I think these people where using their alley way to store stuff. :)
